Does anybody know if this is possible.
Equation as follows.
aSin(20degrees) + bSin(40degrees) + cSin(60degrees) = answer
If the anwser was given in decimal form, is it possible to derive what 'a', 'b', and 'c' are ?, since we already know what the phases are for each.
I recall something about frequency division multiplexing using fast fourier transforms or something like that. But can't quite wrap my head around it.
If there was one signal say 'aSin(20degrees)', then it's simply,
- multiplying the signal with a reference signal that's in phase with signal 'a' with unity amplitude, in this case Sin(20degrees).
- take the average of each resulting product
- double the average, and you have the answer to 'a'.
But what about if it's more then one signal ?
like the one mentioned above,
aSin(20degrees) + bSrin(40degrees) + .....etc
thanks in advance.
