Second order circuits, i.e. circuits with second order transfer functions play a significant role in active filter design. Second order circuits are usually referred to as biquads and can be implemented using one ore more operational amplifiers. The lowpass, highpass, bandpass and band-reject second order functions are examined and the most popular and useful circuits that realize such functions are presented together with their design equations.
