  • The Delta Function and Impulse Response

    For this reason, the delta function is frequently called the unit impulse. The second term defined in Fig. 61 is the impulse response. As the name suggests, the impulse response is the signal that exits a system when a delta function (unit impulse) is the input. If two systems are different in any way, they will have different impulse responses.
