Let’s demonstrate this in Python implementation using sine wave.
WebbThe first 1024 bytes went into the first FFT (first frame), the second 1024 bytes into the second FFT (second frame), etc.This method of viewing time-varying signals has a fundamental limitation. The amount of time required to digitize all the samples of the input signal required to fill one FFT frame defines the shortest resolvable time event.
