def bode(self, w=None, n=100) 

Description

bode.__doc__

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

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

        Examples
        --------
        >>> from scipy import signal
        >>> import matplotlib.pyplot as plt

        Construct the transfer function :math:`H(z) = \frac{1}{z^2 + 2z + 3}`
        with sampling time 0.5s:

        >>> sys = signal.TransferFunction([1], [1, 2, 3], dt=0.5)

        Equivalent: signal.dbode(sys)

        >>> 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()
