commpy.filters.rcosfilter

rcosfilter(N, alpha, Ts, Fs)

Generates a raised cosine (RC) 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 :

h_rc : 1-D ndarray (float)

Impulse response of the raised cosine filter.

time_idx : 1-D ndarray (float)

Array containing the time indices, in seconds, for the impulse response.
