scipy.signal.impulse

scipy.signal.impulse(system, X0=None, T=None, N=None)

Impulse response of continuous-time system.

Parameters :

system : LTI class or tuple

If specified as a tuple, the system is described as (num, den), (zero, pole, gain), or (A, B, C, D).

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 : ndarray

A 1-D array containing the impulse response of the system (except for singularities at zero).
