"WebThe sampling process provides the bridge between continuous-time (CT) and discrete-time (DT) signals. Sampling records discrete values of a CT signal at periodic instants of time. Sampling opens up possibility of processing CT signals through finite impulse response (FIR) and infinite impulse response (IIR) filters. " - Signal sampling theory
