// TODO: put prefixes on these names.
float window (bp_window_t type, int size, int j);
New AFSK demodulators. 'A' uses mark and space filters but simpler and cleaner than earlier attempts. New 'B' uses a different technique where the demodulated signal is proportional to the frequency.

void gen_lowpass (float fc, float *lp_filter, int filter_size, bp_window_t wtype);
New "-g" option for direwolf and atest to force G3RUH modem and override default for the speed. atest -h will display frame as hexadecimal bytes.

void gen_bandpass (float f1, float f2, float *bp_filter, int filter_size, bp_window_t wtype);
void gen_ms (int fc, int samples_per_sec, float *sin_table, float *cos_table, int filter_size, int wtype);
