Systems – Time Domain (Audio, L5-9)

This demo shows the impulse response \(h(t)\) of an LTI-system as well as the input signal \(x(t)\) and the output signal \(y(t) = x(t) \ast h(t)\). Select the input signal and impulse response to hear how the listening experience is affected by the system for different audio signals.

x(t), h(t), y(t)=x*h
