Webideal lowpass filteris the well known sinc function sinc (5.9) where is the total normalized bandwidthof the lowpass filter in Hz (counting both negative and positive frequencies), and denotes the cut-off frequency in Hz. As noted earlier, we cannot implement this filter in practice because it is noncausal and infinitely long.
