Figure 2.16 Fourier coefficients of the discrete transform viewed as corrupted estimate forthe continuous Fourier transform: (a) x(t) and Fourier transform X(f ), (b) unit amplitudewindow w(t) and W(f ), (c) convolution of x(t) and w(f ), (d) discrete sampling function,(e) convolution x(t), w(t), and c(t), and (f) discrete bandwidth limited function based on (e).Source: Ref.
