scipy.signal.lti.

lti.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 bode for details.

Examples

from scipy import signal import matplotlib.pyplot as plt

sys = signal.TransferFunction([1], [1, 1]) w, mag, phase = sys.bode()

plt.figure() plt.semilogx(w, mag) # Bode magnitude plot plt.figure() plt.semilogx(w, phase) # Bode phase plot plt.show()
