In Matlab, I frequently compute power spectra using Welch\'s method (pwelch), which I then display on a log-log plot.The frequencies estimated by pwelch are equally spaced, yet logarithmically spaced
It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical andcannot be reasonably answered in its current form. For help clari
