Overview

COEFFICIENT-CALC (TIBQ) calculates the coefficients for the digital filter biquad transfer function implemented in TI audio codecs. The characteristics of the digital filter are adjusted by selecting a filter type and moving a control point within a window that shows the transfer function gain and phase plot.
