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

Impulse response of continuous-time system.

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).
