 Filtering is a fundamental aspect of signal processing ,which involves the manipulation of the spectrum of a signal by passing or blocking certain portions of the spectrum, depending on the frequency of those portions. Filters are designed according to what kind of manipulation of the signal is required for a particular application. Digital filters are implemented using three fundamental building blocks: an adder, a multiplier, and a delay element. This paper discusses the design and implementation of Digital Filters using a programmed PIC microcontroller, and concludes with a discussion on how the various filters can be modeled. simulated and analyzed using Matlab, a software package, The design options in Matlab allow the user to either create codes for designing filters that calls built-in functions.
