scipy.signal.impulse¶

scipy.signal.impulse(system, X0=None, T=None, N=None)[source]¶

Impulse response of continuous-time system.

Parameters :

Parameters :	system : an instance of the LTI class or a tuple of array_like describing the system. The following gives the number of elements in the tuple and the interpretation: 2 (num, den) 3 (zeros, poles, gain) 4 (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).
