1. In signal processing and systems theory, the output of a system when subjected to a brief input signal (impulse), used to characterize the system's behavior
The impulse response of the filter reveals its frequency characteristics.
A resposta de impulso do filtro revela suas características de frequência.
2. In acoustics, the characteristic sound produced by a room or space when exposed to a sudden sound stimulus
Engineers measure the impulse response to evaluate the room's acoustics.
