4. Design and Implement Digital Filters, Including FIR and IIR Filters, for Signal Processing in Communication Applications

Digital filters are essential components in signal processing for communication systems, focusing on modifying and enhancing digital signals. The chapter discusses the two main types of filters—FIR and IIR—alongside their design techniques, features, and applications. FIR filters ensure stability and linear phase designs, making them straightforward to implement, while IIR filters provide efficiency and approximations of analog filters. Proper attention to design parameters and implementation strategies is crucial for effective real-time processing.
