Op Amps: Resonant EQ

In this video we examine the construction of an op amp resonant equalizer. Typically, this is used to create a midrange control, allowing the user to boost or cut the level of a certain range of frequencies, rather like common bass and treble controls. It is strongly suggested that you watch the video covering bass and treble EQ circuitry before watching this video.
