Higher order filters are normally designed by cascading second order filters
and, if needed, one first- order filter. Design a third order Butterworth Lowpass
Filter using FilterPro and obtain the frequency response as well as the
transient response of the filter. The specifications are bandwidth of the filter

The circuit described in Figure 4.1 is a universal active filter circuit. While
this circuit can be built with OP-Amps, a specialized IC called UAF42 from
Texas Instruments provides the functionality of the Universal Active Filter.
We encourage you to use this circuit and understand its function.
Datasheet of UAF42 is available from http://www.ti.com.
Also refer to the application notes [7], [11], and [12].
