sig_tone_flat_coeffs_t Struct Reference

The coefficient set for a bi-quad that makes a signalling flat filter. Some signalling tone schemes require such a filter, and some don't. It is termed a flat filter, to distinguish it from the sharp filter, but obviously it is not actually flat. It is a broad band weighting filter. More...
