Signature

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

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

w : array_like, optional: Array of frequencies (in rad/s). Magnitude and phase data is calculated for every value in this array. If not given a reasonable set will be calculated.
n : int, optional: Number of frequency points to compute if w is not given. The n frequencies are logarithmically spaced in an interval chosen to include the influence of the poles and zeros of the system. Defaults to 100.
