commpy.filters.rrcosfilter

rrcosfilter(N, alpha, Ts, Fs)

Generates a root raised cosine (RRC) filter (FIR) impulse response.

Parameters:

• N (int) – Length of the filter in samples.
• alpha (float) – Roll off factor (Valid values are [0, 1]).
• Ts (float) – Symbol period in seconds.
• Fs (float) – Sampling Rate in Hz.

Returns:

• time_idx (1-D ndarray of floats) – Array containing the time indices, in seconds, for the impulse response.
• h_rrc (1-D ndarray of floats) – Impulse response of the root raised cosine filter.
