scipy.signal.StateSpace.bode

StateSpace.bode(w=None, n=100)[source]

Calculate Bode magnitude and phase data of a continuous-time system.

Returns a 3-tuple containing arrays of frequencies [rad/s], magnitude [dB] and phase [deg]. See scipy.signal.bode for details.

Notes

New in version 0.11.0.

Examples

>>> from scipy import signal
>>> import matplotlib.pyplot as plt
>>> s1 = signal.lti([1], [1, 1])
>>> w, mag, phase = s1.bode()
>>> plt.figure()
>>> plt.semilogx(w, mag)    # Bode magnitude plot
>>> plt.figure()
>>> plt.semilogx(w, phase)  # Bode phase plot
>>> plt.show()
