... This characteristic response shape is termed the impulse response . This is a key concept in signal processing — the impulse response is that response produced by a system (in this case, the electroacoustic ... thus the impulse response cannot be measured directly. Rather, we use methods such as that described using white noise, to estimate the impulse response of the system. Chapt...
