Q387 : Purpose of Maximum Number of Frequency Samples

Question
How can I select a proper value for the "Maximum Number of Frequency Samples" in FFTSES?


Answer
The "Maximum Number of Frequency Samples..." is used as a rough estimate of the number of recommended frequencies that the program should generate. The default value is usually OK. A larger value will instruct the program to look more aggressively for "peaks and valleys" in the input data (which is what is used to determine the recommended frequencies). You should modify this value only if you find that the number of computation frequencies recommended by the program is always too small, and misses some important resonance effects.
