ABSTRACT
The TMS320C6711 DSK has the capability of real-time signal processing operations, the most important of which is digital filtering. Filtering is one of the most widely used applications in Communication Engineering [1]. Some of the practical applications of filtering are listed below:
Demodulation of AM and FM signals• : Low pass filtering is utilized to recover baseband audio or video signal from the modulated signal. Stereo generation• : In stereo systems, the basic audio signal is separated into low-frequency and high-frequency components using filter banks, amplified, and then synthesized to generate the stereo signal. Filtering of noise• : Communications signals such as audio and video signals are corrupted by various sources of noise during propagation through communication channels. Filters are very useful in signal restoration and signal enhancement.
