WebJul 22, 2016 · 3 Answers. Sampling discrete-time signals, i.e., using only every N t h sample of a sequence of samples, is useful for efficiently processing, transmitting, or storing information, if we can be sure that the sampling rate can be reduced without significant loss of information. This process is called decimation. WebFigure P18.7 shows a system that processes continuous-time signals using a digital filter. The digital filter h[n] is linear and causal with difference equation y[n] = -y[n -1]+x[n] For input signals that are bandlimited so that Xe(w) = 0 for I l > ir/T, the system is equivalent to a continuous-time LTI system.
