Digital Filters - III.
We are now ready to consider the systematic design of non-recursive filters.
The design method is based on Figure 16-1, which has 6 parts. On the upper
left is a sketch of the ideal filter you wish to have. It can be a low pass,
a high pass, a band pass, a band stop, a notch filter, or even a differentiator.
For other than differentiator filters you usually want either 0 or 1 as the height
in the various intervals, while for the differentiator you want i_w since the
derivative of the eigenfunction is d/dt[exp(i_wt)]=(i_w)exp(i_wt).
