Window Function Fft Calculate Low Pass Filter Time Constant

Introduction & Importance

The window function FFT low pass filter time constant is a crucial parameter in signal processing, particularly in the analysis of discrete-time signals using the Fast Fourier Transform (FFT) algorithm. It determines the transition bandwidth of the low pass filter applied to the signal before the FFT is computed.
