scipy.signal.dstep¶

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

Step response of discrete-time system.

Parameters :

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.

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.
