I have a set of numerical signals that give me a set of zeros calculated based on some numerical procedure. I make a histogram of those zeros.
Here, a following problem arises:
If the histogram resolution is declared greater than sampling rate for signals’ data some oscillation in the histogram starts to appear. A frequency of it equals to the sampling rate for the signal.
- Is this a common effect?
- Is a histogram bin size related in some way to a sampling rate?
