then the output of the circuit has a pole at frequencies from 1 kHz

to 100 kHz for V

The performance

of this low-pass filter is illustrated in Figure 20.

With this approach, it is possible to construct parametric biquad

filters whose parameters (center frequency, passband gain, and Q)

can be adjusted with dc control voltages.
