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 :

h_rrc : 1-D ndarray of floats

Impulse response of the root raised cosine filter.

time_idx : 1-D ndarray of floats

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