Detailed Description

This class adapts a gnuradio gr_freq_xlating_fir_filter designed with pm_remez.

Construct a FIR filter with the given taps and a composite frequency translation that shifts intermediate_freq_ down to zero Hz. The frequency translation logically comes before the filtering operation.

See Parks-McClellan FIR filter design, https://en.wikipedia.org/wiki/Parks-McClellan_filter_design_algorithm Calculates the optimal (in the Chebyshev/minimax sense) FIR filter impulse response given a set of band edges, the desired response on those bands, and the weight given to the error in those bands.
