Rework of the RollOff() roll_off() transform #209

Closed MattCarrickPL closed 11 months ago

MattCarrickPL commented 12 months ago

Rework of the roll-off transform. Previously was a sharp filter with a cutoff very close to -fs/2 and +fs/2 with sidelobe attenuation around 100 dB. Now is a more gentle implementation of an LPF which has between 0 dB and 12 dB sidelobe attenuation and a slight frequency offset of the filter. The intent is to implement LPF affects from digital filtering and/or analog components.

Implements #201
