FIR filter design using the window method.
Cutoff frequencies of the filter, specified in units of "nyquist." The frequencies should all be positive and monotonically increasing. The frequencies must lie between (0, nyquist). 0 and nyquist should not be included in this array.
If true (default), the gain at frequency 0 (ie the "DC gain") is 1, if false, 0.
The nyquist frequency, default is 1.
Whether to scale the coefficiency so that frequency response is unity at either (A) 0 if zeroPass is true or (B) at nyquist if the first passband ends at nyquist, or (C) the center of the first passband. Default is true.
