State Variable Filter

A state variable filter requires three op amps. One convenient way to build state variable filters is with a quad op

amp, such as the LMV324 (Figure 63).

This circuit can simultaneously represent a low-pass filter, high-pass filter, and bandpass filter at three different

outputs. The equations for these functions are listed below. It is also called "Bi-Quad" active filter as it can

produce a transfer function which is quadratic in both numerator and denominator.
