As the title states. Imo monitoring ripple voltage using an oscilloscope at both the input and output whilst a function generator inputs "noise" (sine wave from 10Hz - 10MHz) onto the input DC line via coupled inductor/capacitor or high slew rate opamp circuit. Is this right? If so, in detail how do you couple the noise to the input?
I love being a cna. I love helping. But maybe it's just where I've worked. But I'm starting to loath it. I'm never less then a 1:14 ratio. Most the places I've worked won't even supply anything but briefs and linen. I have to supply my own soaps and wipes. Often I start at a place and I go to Excell with my assignment and it just ends up with higher and higher rates for me. Everywhere is mainly staffed by agency and I'm the only staff. The agency people making double my pay pawn off there duties to me by going to my superior. I've quit three places in the last 6 months because of this. On top of it I'm often sucked into doubles back to back or coming in on my days off because these places allow others to call off. I live doing the care but I've been a cna less then a year and I don't want to do it anymore. Most the residents are good and are happy I happy but there's a few that think I'm there to be there servant. Had a guy at my last job say even through he was compatible of feeding himself I should feed him when I refused because I have 4 feeds already he went to my supervisor and I was written up. The nurses since I have more then just a cna (I hold a variety of certs) are constantly asking me to take on parts of their loads but are out of my scope of practice. I feel stuck. Recently I was at a facility that let all the kitchen go home early on Christmas day. I and the other cnas had to make deliver and feed 100 residents on top of our other duties. Needless to say I'm jobless since the 26. Does it get any better? Am I just picking the wrong places to work? Or is it cause I'm new and haven't built up a tolerance to the mistreatment? I've been working at Nursing homes, alfs and agencies. Any tips where maybe it won't be so terrible on me?
While the title may imply that I am in some ways biased, or upset, towards women, as I have been rejected many times, I now see that such a thing is ultimately useless, and petty. My love life has always been, as some might say, nonexistent. I’m told by many that ‘some lucky woman will swoop you up’, but yet I remain alone, year after year. In some ways this may be understandable, as i am prone to odd behaviorisms, and at times, it seems even self sabotage. Though ultimately I am lonely, by my ratio of 6/5 rejections (yes, it would be quite the long story to explain), I’ve found comfort in friendship. However, the feeling of consistent rejection has left me feeling rather empty. Considering how many times I have had to move all over the country, and start anew, I fail to see how each time I have made the same failures. Loneliness is not something I would wish upon any person-even those who portray themselves in an unsightly manner- because in the grand scheme of things, it’s clear that all they want is companionship. But through this I realized why I have never been in a relationship. it is because those around me would not like to be with me. Coming to terms with this was not easy, but I emerged a better man when I came to understand this, and accept it. I have finally come to peace with the fact that I will never be in a relationship. Though it is upsetting, I understand why.
To those out there in the same pain i suffered, remember, the light at the end of the tunnel is bright, but it will be your own flame, which will illuminate your path.
The British were really awful around the turn of the 20th century. Especially how they treated their colonies looking for independence and losing the grip on their powerful empire. They really tried to hold onto every inch of their empire with extreme violence, bloodshed and racist ideologies. The perception of Britain joining the war to do good in the world and fight for freedom when they were incredibly racist and cruel themselves doesn’t add for me? There was a lot of sympathy towards fascism in the upper echelons of British society. A lot of Nazi beliefs overlap in terms of how real world British colonialism worked? Is the bravery of the British war effort a revisionist excercise in making Britain look good post war? Were they more so concerned with Germany taking their place in the world and that is the real reason they entered world war 2?

I am following a tutorial and they use the above testbench to find the CMRR of a folded-cascode opamp. The circuit on the right simulates the AOL gain and the circuit on the left simulates the ACM gain. Both are fed by the same 1V amplitude AC signal (net names into the non-inverting terminal are the same). The formula shown above is then used to plot CMRR in dB.
The feedback resistor and capacitor in both schematics are 1G and 10uF respectively. Now for the schematic on the right which simulates AOL, the RC in the feed back path introduces a low frequency zero at 1/2piRC (some zero at uHz)
I am not sure why the schematic on the left for ACM gain has the capacitor between both inputs. As far as I have seen in ACM simulation, we short the two inputs and drive it with a small-signal perturbation when the opamp is in open-loop. Does the RC network for the schematic on the left also introduce a low frequency zero? If yes, then at what frequency?
Can someone explain the circuit on the left and how it calculates the ACM gain?
Also how would the testbenches look if you were simulating ACM and AOL for a fully differential circuit? Something with a sketch would be useful.
Currently there are 226 operators (going by CN server), with 45 of them being male characters (~20% of the total) and the rest being female characters + conviction. This number includes all reserve operators found in IS as well.
I'd like to change my theme team but losing half the training I've invested sucks.
In this subreddit I often see "I wouldn't go below X watts" kinds of replies to build posts, with X usually being a LOT more than what the build would theoretically and realistically consume.
I would understand if its for a 3080 or a 6800XT level and beyond build, if OP is planning to upgrade to a higher tier card later on, will have multiple GPUs in the build, or do some overclocking and wants the headroom.
But I too often find these replies for builds with a 16 series card up to the mid-high 3060Ti/3070/6700XT. Often paired with (solid mid-range) 65W CPUs like the 5600X or 11400F.
It annoyingly itches me when people do this, and my two arguments everytime are:
- TechYesCity ran and stressed a 2080Ti (250W) and a 3950X (105W) on a single 450W PSU, which turned out fine. Totally an exaggeration and you definitely shouldn't get a 450W PSU for this level of a build, but it proves a point. https://youtu.be/wg6pz7YTxyA
- My gaming rig has a 6700XT and a 5700 (old card I use to mine). 6700XT consumes as low as 90W mining and as high as 200W gaming, while the 5700 always mines at 110W. Have been running the rig like this since last May, its been working without problems.
- On top of that, the average gamer realistically never maxes out both CPU and GPU at the same time to reach their combined TDPs.
Rather I believe that the quality of the power supply should take priority over how many watts can be pulled from it. I'd rather a 500W PSU from EVGA with tons of positive reviews than a random-brand no-review 1000W unit.
It gets kind of tiring having to type this over and over again whenever this happens, hence the rant. Stop overspending/suggesting others to overspend on their power supplies!
But what do you think? Open to being told I'm wrong, tell me why!
Edit: What I'm saying mostly applies to the mid-high builds and below.
If you're already spending 3-5 grand on a powerful build, then getting a PSU that'll run it well for years to come and be ready for any future (high wattage component) upgrades doesn't cost that much more and makes sense.
I think that 500-650W should be the go-to for most average builds. CPUs like the 5600X and 11400F or GPUs like the 6700XT and 3070.
Coming from running one 5700 to adding a 6700XT to run with it on a single 650W, I can say 650W already provides a lot of headroom for the mid-high end build most people are going for.
Edit 2: Watching GamersNexus' video, I'm reassured an

What are everyone's thoughts on this? Because of the stimulus and people sitting on cash it seems like earnings are way down but the fundamentals of the economy are still strong and this should not lead to a recession but would love to hear everyone's thoughts..

So I finally have an okay city going. I had a mass die off to starvation twice, in the early days and then around year 16.
Does anyone have any educated numbers as to what amount of inventory a city needs to population mass?
For instance, I take the total number of Working Citizens ( THIS NUMBER / # / # ) and divide it by 2 to figure out how many houses I need.
Like how much food should I always have in that block per TOTAL NUMBER of People, how much tools, how much firewood, etc.
Does anyone have a table worked out with data?
Im currently thinking about getting myself an E39, prices are still alright in Germany, and theres pretty much a lot of em with every engine avaliable on the used market. Now im not really sure which model to get, my heart obviously screams M5, but thats sadly not an option since im still in college. My first choice would be 528i, or is there anything better on the power to reliability scale? V8s are sadly out of the question because fuel prices here are ridicoulous at the moment.
