WebIf we apply an impulse at the input of a system, the output response is known as the system’s impulse response: h(t) for continuous time, and h[n] of discrete time. We have demonstrated in Lecture 3 that the Fourier transform of a unit impulse is a constant (of 1), meaning that an impulse contains ALL frequency components.
