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. 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.
