The stated syllabus are as follows... Operation, application and uses of the following filters: low pass, high pass, band pass, band stop.

A. Introduction
If we relate the word filter to the mechanical application, like the water filter, it function include the removal of unwanted particles or impurities. Depending of the type of filter used, it can prevent small or larger particles to pass through.

In we apply the concept to the electronic application, then filters will have the following characteristics.....
- high pass - allows high frequencies to pass through
- low pass  - allows low frequency to pass through
- band pass - allows norrow band of frequencies to pass through
- band stop - stop the flow of narrow band of frequencies.
