See my other answer - I meant applying it analytically. Your idea is interesting though, and I do know that it should be possible to build a Fourier transform analog circuit. Once you sample though you will be subject to having a nyquist frequency and introducing noise to your signal and the advantage of performing it with an analog circuit will be lost.
- funklute 7y agoYea, actually I thought a bit more about it as well, and any real (analog) circuit will have a frequency response that tapers of to zero as the frequency goes to infinity. So that basically determines a Nyquist frequency for any analog circuit, even if that frequency is so high that it has no practical implications.
