www.robots.ox.ac.ukIn the time domain, a system is described by its Impulse Response Function h(t). This function literally describes the response of system at time tto an unit impulse or -function input administered at time t= 0. Suppose that \now" is time t, and you administered an impulse to the system at time ˝in the past. The response now is y(t) = h(t ...
