scipy.signal.dlti.

freqresp

dlti.freqresp(w=None, n=10000, whole=False)

Calculate the frequency response of a discrete-time system.

Parameters:

warray_like, optional

Array of frequencies (in radians/sample). Magnitude and phase data is calculated for every value in this array. If not given a reasonable set will be calculated.

nint, optional

Number of frequency points to compute if w is not given. The n frequencies are logarithmically spaced in an interval chosen to include the influence of the poles and zeros of the system.

wholebool, optional

Normally, if w is not given, frequencies are computed from 0 to the Nyquist frequency, pi radians/sample (upper-half of unit-circle). If whole is True, compute frequencies from 0 to 2*pi radians/sample.

Returns:

w1D ndarray

Frequency array [radians/sample]

H1D ndarray

Array of complex magnitude values
