# scipy.signal.dstep

`scipy.signal.``dstep`(system, x0=None, t=None, n=None)

  Step response of discrete-time system.

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