Abstract
A parametric equalizer includes a first parametric equalizer circuit, a second parametric equalizer circuit, a first multiplication circuit, a second multiplication circuit, an addition circuit, and a weighting control circuit. The first parametric equalizer circuit processes an input signal to output a first output signal. The second parametric equalizer circuit processes the input signal to output a second output signal. The first multiplication circuit multiplies the first output signal and a first weighting value to generate a first adjusted output signal. The second multiplication circuit multiplies the second output signal and a second weighting value to generate a second adjusted output signal. The addition circuit combines the first adjusted output signal and the second adjusted output signal to generate an equalizer output signal. The weighting control circuit dynamically adjusts the first weighting value and the second weighting value according to the equalizer output signal.
