Op Amps: Parametric EQ

At last, we reach the parametric audio equalizer. This version is based on the four op amp state variable band pass filter. It features independently adjustable center frequency, cut and boost, and Q (bandwidth). Before watching this video, it is strongly suggested that you watch the videos covering the other audio EQ circuits and the state variable filter in the Op Amps playlist.
