What is FFT low-pass filter?

18.2 FFT Filters

Low-pass filters block all frequency components above the cutoff frequency, allowing only the low frequency components to pass. High-pass filters are just the opposite and block frequency components that are below the cutoff frequency.

How does low-pass filter affect Fourier Transform?

The frequency contents of the signal and their powers can be obtained through operations such as the Fast Fourier Transform (FFT). A low-pass filter passes relatively low frequency components in the signal but stops the high frequency components. The so-called cutoff frequency divides the pass band and the stop band.
