Oh, yeah, I had to google that too, because I am not a native speaker. "The dad joke is a pejorative term used to describe a corny, unfunny, or predictable joke, typically a pun. Generally inoffensive, dad jokes are traditionally told by fathers among family, either with sincere humorous intent, or to intentionally provoke a negative reaction to its "dagginess"."

@luketorpedo6 жыл бұрын
Far as I can tell here, I believe those harmonics you are seeing would be down to the actual signal being generated being a square wave. This is pretty clear by every second multiple of the fundamental frequency having a higher spike in amplitude which summed make a square wave. I'm not sure why there are smaller spikes between, but they won't have much effect given a small reduction in dB is a huge reduction in signal in real terms. I would guess the low bandwidth of the oscilloscope in comparison to the 2nd harmonic is probably why the scope is outputting a sine rather than the square wave the signal analysis suggests is present.

I think youd need to isolate the frequency, amplify it a bit and make a transmitter. I think either or a combination of a RF Filter, Low and/or High pass filters. never tried, but I know its posible and if you try it localy, with a tiny amplifier so within 10 menters youd jam, it probably is allowed as "research". Note that bluetooth is on 2.5Ghz as Wifi is aswell (later wifi is also on the 5Ghz. ) jam those and your sure some device cant talk good anymore. I might be wrong tho, im not a licensed radio amateur, just an electronics enthousiast
