Nope, and just how would a simple trig factor, if it were possible, answer his question ? Second, since he won't answer my requests, why should I honor his?
DJ, let's take a look at what was said:
Good morning EE: You posted -->Whenever you add two frequencies, you end up with four frequencies: the original two frequencies, plus the sum frequency and the difference frequency. The sum would be a higher frequency, and the difference a lower
*************
You are correct, plus the intermodulation of their combinations and on to infinity.
EE's statement was wrong; adding 2 frequencies does not produce 2 add'l frequencies. Because he knows what he is talking about, he recognized his mistake, and immediately corrected it.
Your "agreement" added even more wrong. And because you didn't know what you were talking about, you defended your mistake by doing the only thing you could do: toss out an irrelevant web link.
Then you said...
Heterodyning --> In radio and signal processing, heterodyning is the generation of new 'frequencies' by mixing two oscillating waveforms. ...
The Subharmonics / harmonics that are produced causes two tones to form a second pair of tones, one being a difference between the two and the other being the sum. the sub harmonic / harmonic combined with one of the orig frequencies again produces two more frequencies and on to an infinite no of combinations, all progressively weaker
If you knew anything about signals, you wouldn't have said this. For those who know what they are talking about, the mathematics of signals (frequencies) using sines & cosines is easy. Since you have no idea how to do this, your response is limited to
Radio theory doesn't apply here, so forget it.
Besides directly contradicting your own prior post (I highlighted that little bit so you wouldn't be tempted to pull an Artie), signal math works the same way whether your dealing with radio, sound, light, or water waves. The signal math won't work, of course, for WishScience applications, where claims are pulled from thin air, with just enough misapplied scientific terminology to sound technically impressive.
So I say again... Show Me. If adding 2 frequencies produces "intermodulations to infinity," then show me the math that supports this claim. Here, I'll get ya started:
sin(w1t) + sin(w2t) = ??
Or, if heterodyning (multiplying) 2 frequencies produces an "infinite no of combinations," then the math should be simple:
sin(w1t) * sin(w2t) = ??
This is Signals 101, simple stuff. Remember, you didn't preface your claims with your usual "
couldn't it be possible...?" disclaimer. You were saying, "
this is what happens." But it's not what happens, so it's all disinformation. How in the world can anyone seriously discuss these kinds of topics when people just freely toss around nonsense?
Show me, and stop blaming me for your inability to do so. You are free to retract your claims; a simple "
I really don't know" will suffice.
