scipy.signal.dimpulse¶

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

Impulse response of discrete-time system.

Parameters :

system : tuple

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. 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).

Returns :

t : ndarray

A 1-D array of time points.

yout : tuple of array_like

Step response of system. Each element of the tuple represents the output of the system based on an impulse in each input.
