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.
