ABSTRACT
Analog filters are essential in many different systems that electrical engineers are required to design in their engineering career. This chapter presents steps to design other types of filters from the low-pass filter by writing the frequency transfer function. It discusses and talk a lot about digital systems nowadays, these systems always contain one or more analog filters internally or an interface with the analog world. Filters are widely used in communication technology as well as in other applications. There are three basic steps to synthesize any type of low-pass filters. The first step is calculating the order of a low-pass filter. The second step is calculating poles and zeros of a low-pass filter. The third step is designing circuits to meet pole and zero locations; however, this part is another topic of analog filters, so it will be not be covered in this work.
