scipy.signal.lti.bode

lti.bode(w=None, n=100)

Calculate bode magnitude and phase data.

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

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()
