# scipy.signal.dstep¶

scipy.signal.dstep(system, x0=None, t=None, n=None)[source]

Step response of discrete-time system.

Parameters: system : tuple of array_like A tuple describing the system. The following gives the number of elements in the tuple and the interpretation: 1: (instance of dlti) 3: (num, den, dt) 4: (zeros, poles, gain, dt) 5: (A, B, C, D, dt) x0 : array_like, optional Initial state-vector. Defaults to zero. t : array_like, optional Time points. Computed if not given. n : int, optional The number of time points to compute (if t is not given). tout : ndarray Output time points, as a 1-D array. yout : tuple of ndarray Step response of system. Each element of the tuple represents the output of the system based on a step response to each input.
