# bode

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

  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()
