Been meditating on this recently...
Nyquist theorem states bandwidth of sampled signal to be 1/2 of sampling frequency. But the maximum frequency in the passband can then only be a sinewave, surely? Anything more complex would have higher frequency content? Check me on this.
My thinking is that as one approaches the fmax signal frequency, the less complex it can be. So, music signals being complex (fundamental plus harmonics), what would be the practical bandwidth for a music signal? Conversely, how much loss of detail can be tolerated?
Or have I got it all wrong?
