- /* One Zero Filter Class, */
- /* by Perry R. Cook, 1995-96 */
- /* The parameter gain is an additional */
- /* gain parameter applied to the filter */
- /* on top of the normalization that takes */
- /* place automatically. So the net max */
- /* gain through the system equals the */
- /* value of gain. sgain is the combina- */
- /* tion of gain and the normalization */
- /* parameter, so if you set the poleCoeff */
- /* to alpha, sgain is always set to */
- /* gain / (1.0 - fabs(alpha)). */
