Typical Applications (continued)

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.

9.2.6.1 Detailed Design Procedure

Assume the system design requires a bandpass filter with f O = 1 kHz and Q = 50. What needs to be calculated

are capacitor and resistor values.

First choose convenient values for C1, R1 and R2:

C1 = 1200 pF
