- scipy.signal.impulse(system, X0=None, T=None, N=None)¶
Impulse response of continuous-time system.
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).
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).
