Unformatted text preview: signals A discretetime signal is the result of sampling a continuous signal at defined intervals. z = f[n] = f(nT) Domain of signal is set of discrete integer values Range can be either continuous or discrete values Signal can take on a finite number of values 4 EE 200 Signals Spatial signals can be sampled in two dimensions z = f[n,m] = f(nS x , mS y ) The signal range can be discrete For any sampled signal, is it possible to recover the continuous signal from the discrete one? Answer: sort of...
