# scipy.signal.dimpulse¶

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

Impulse response of discrete-time system.

Parameters
systemtuple of array_like or instance of dlti

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)

x0array_like, optional

Initial state-vector. Defaults to zero.

tarray_like, optional

Time points. Computed if not given.

nint, optional

The number of time points to compute (if t is not given).

Returns
toutndarray

Time values for the output, as a 1-D array.

youttuple of ndarray

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