How does component Fast Fourier Transform measure frequency?
Hello. I just can't understand how does component "Fast Fourier Transform" measure frequency? Maybe there are some formula for this or picture illustrating this like in the "Frequency and Incremental Phase Measurement". There are picture of frequency measuring in "Frequency and Incremental Phase Measurement", bit I don`t see something like this in "Fast Fourier Transform". Thank you for answers!
