commpy.filters.rectfilter

rectfilter(N, Ts, Fs)

Generates a rectangular filter (FIR) impulse response.

Parameters:

• N (int) – Length of the filter in samples.
• Ts (float) – Symbol period in seconds.
• Fs (float) – Sampling Rate in Hz.

Returns:

• time_index (1-D ndarray of floats) – Array containing the time indices for the impulse response.
• h_rect (1-D ndarray of floats) – Impulse response of the rectangular filter.
