Regarding "Are we intuitively comfortable with the fact that 2 completely different signals will have identical spectrums?"They have identical magnitudes, but different...
Milad,In addition to the replies below it may help to consider the difference between group delay and phase delay (aka time delay). There is a detailed discussion...
Tim, you have some good points.Also I would add that the linear interpolation I referred to is not resampling by adding zeros and filtering. As Vincent pointed out,...
Hi Vincent,First, this is not harmonic distortion.  The spurious signals you see are phase modulation. The sidebands appear on harmonics because of the numbers...

To elaborate, Class C "horribly nonlinear" amps have been used in FM broadcast transmitters, FM land mobile radios, GMSK cellphones, FSK and PSK data communications...

Re: Spurious when Fs/F is not an integer

To elaborate on why phase dither is necessary -You have a phase accumulator with a very large number of bits (or digits) to get 10 Hz of resolution at 500MHz. But...
