- cupyx.scipy.signal.bode(system, w=None, n=100)#
Calculate Bode magnitude and phase data of a continuous-time system.
system (an instance of the LTI class or a tuple describing the system.) –
The following gives the number of elements in the tuple and the interpretation:
1 (instance of lti)
2 (num, den)
3 (zeros, poles, gain)
4 (A, B, C, D)
w (array_like, optional) – Array of frequencies (in rad/s). Magnitude and phase data is calculated for every value in this array. If not given a reasonable set will be calculated.
n (int, 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.
w (1D ndarray) – Frequency array [rad/s]
mag (1D ndarray) – Magnitude array [dB]
phase (1D ndarray) – Phase array [deg]
If (num, den) is passed in for
system, coefficients for both the numerator and denominator should be specified in descending exponent order (e.g.
s^2 + 3s + 5would be represented as
[1, 3, 5]).
