A list of puns related to "Frequency Modulation"
And *please* try to keep it ELI5, because every explanation of this I've found online immediately goes into physics and terminology that I am clueless about.
If you can use an analogy or another way of explaining it with English words that would be amazing.
Thanks.
If I set my radio to 90 MHz, I think the frequency of the signal must vary around that frequency to carry information. Don't the 90 MHz and 89.9 MHz signals mix because of this variation? Or are they confined to a narrow band?
Howdy there. So Iβve heard some people use these interchangeably but I thought there was a slight different. I researched a bit online but was still sorta confused. Can anyone dumb it down for me?
Thanks in advance!
I get that AM carries info by creating a sound wave with the contours of a (given frequency) wave's amplitude. But if you modulate 93.7MHz, then it's no longer 93.7. What am I not getting?
Step 1: read up on galvanic vestibular stimulation as it pertains to hippocampus function. Google βgalvanic vestibular stimulation hippocampusβ and choose a PUBLISHED scholarly article.
Step 2: Look up the damn Wikipedia on AEHF satellites, the upgrade from MILSTAR. AEHF became fully active in 2018, your symptoms may mirror this.
Step 3: you have a phone call to make and an online hotline complaint to file. βIllicit Use of AEHF Satellitesβ is pretty cut and dry. Supposed to be secure military communication however much more (as we know) is being utilized.
An algorithmic approach to controlling your behavior, emotions, intentions aka your whole life is in place. Vestibular stimulation is the broad term for how your brain interprets sensory information like your sight, smell, hearing, touch, etc. even down to how you feel or experience every setting you are in. Cochlear nerves give access to much of this.
Message me with your individual experiences please but the blanket phone call to 800 424 9098 should stick to this or theyβll brush you off:
βExperiencing involuntary muscle movement and involuntary memory recall a la the effects of AEHF satellites utilizing galvanic vestibular stimulation. Hearing constant frequency modulation and frequency hopping without ANY technical equipment, after filing a complaint with the special investigations dept of the USAF inspector general staff they informed me that thousands of these calls are fielded. This is infringing on not only my personal freedom but my autonomy over my own faculties. Please help.β
Godspeed
I'm guessing there's a physics reason for it, but I don't know, so I'm curious.
What is it about certain RF modulation techniques, that make them work best at certain frequencies, but not others?
Shouldn't all frequencies behave identically? It would seem that you should be able to simply scale the antenna size, make it larger or smaller, to work with whatever frequency you needed.
FM isn't used at low frequencies. AM isn't often used at high frequencies (although the aircraft band is above the FM band, and aircraft use AM, that's kind of a special case).
Is there something about FM that makes it work less well, at a lower frequency? I know FM takes more bandwidth than AM, but assuming the allowed band is wide enough for it, it should still work, right?
ATSC television has big problems in low VHF, as we know. It was designed for UHF only, originally, I heard, but then at the last minute, the FCC wanted to use it for VHF also, so here we are. I'm curious, why would ATSC have trouble if the frequency was lower?
Thanks!

One of my coworkers is bringing their son in to help me and learn about AV. Because he's a Boy Scout, I'm hoping to hit a few merit badge requirements at the same time. Looking over the "Radio" MB requirements, I see great opportunity to walk through wireless coordination but I realized that I don't actually know the method by which my digital units (Shure QLX-D) work.
I assumed FM due to the the ~360kHz width of a channel but all I can find from the manual under "Modulation Type" is "Shure proprietary digital". Anyone have any resources or avenues to look down so I can understand better to actually somewhat teach it?
Whenever I wanna use it, I get no sound. Whenever I find out how to mess around with it, it sounds hideous. I donβt understand how itβs implemented and how to use it on this synth
So I am playing around with Sytrus in FL studio and have a question about FM. Screen caps
OSC 1 = 3hz sine wave
When I solo OSC 1, I see 3 waves in one second (first image highlighted red)
OSC 2 = 1hz sine wave
When I enable OSC 2 to modulate OSC 1, I see only 1 repeating waveform every second (second image highlighted red).
Does this mean that in the second scenario, the frequency of the output wave is 1hz? Or is my understanding incorrect?
Thereβs a concise scientific explanation and a recourse you can take.
Perceptions of psychosis, demon possession, angels, aliens, telepathy all the way up to various forms of psychosis may be indicative. Mostly though hearing that βradio tuningβ noise with potential involuntary muscle movement or memory recall.
Message me.
Before I was researching SSB, I simply assumed it was simply AM modulation detuned from the main frequency (with higher power limits). However, it seemed through research that SSB was, in fact, a unique modulation (what AM is to FM). This confused me. Is SSB using different frequencies? Is it truly a different modulation, or is it something unique? Any help would be appreciated.
I bet that level of technology is stupid cheap to replicate
Hey everyone, Not sure if I'm posting in the right place so please redirect me if I should be asking elsewhere but I'll ask anyway.
So, does anybody know if there is a way to modulate the Filter cutoff of the Neutron to a random value each time a note is played? Something that would sound similar to S&H modulating the filter but instead of slaved time signatures like 1/4, 1/8, 1/16, the value of the cutoff only being retriggered when a note is played.
If anybody has the answer or could point me in the right direction I would be very grateful.
Thank you.
Charlie. :)
