 112 This filter is a convenience wrapper for an fir filter and a firdes taps generating function.
 113
 114 The decimation paramater becomes interpolation when the filter type is set to interpolating.
 115
 116 Sample rate, cutoff frequency, and transition width are in Hertz.
 117
 118 The beta paramater only applies to the Kaiser window.
