Similar to Calculating the PDF of a waveform from its samples, but for periodic sampled signals, and I just want the peak. Is there a way to calculate the highest inter-sample peak of the reconstructed signal?
For instance, the signal
0, 0, 1, 1, 0, 0 is symmetrical, so you know the intersample peak is between samples 2 and 3, at 2.5, and can be calculated as ... + sinc(-0.5) + sinc(0.5) + sinc(5.5) + sinc(6.5) + ... ≈ 1.24
But is there a way to do this for the general case, when you don't know where the peak occurs?
This page says the MLS has the lowest possible crest factor, but I think for analog use, this isn't actually true, since MLS has strong intersample peaks, >6 dB higher than the samples, and a sweep-like signal like the Newman method has better crest factor.
