MATLAB Code Implementation with Practical Application: Polyphase Filtering for 2x Decimation
Using 2x decimation as a practical example, this analysis explores the fundamental principles and implementation methods of polyphase filtering. The discussion includes MATLAB code demonstrating how polyphase filtering achieves equivalent functionality to traditional FIR filtering while potentially offering superior performance in specific scenarios, with experimental results validating the approach.
An Efficient Filter: CIC (Cascaded Integrator-Comb Filter) and Its Implementation
A widely adopted efficient filtering solution in engineering uses CIC (cascaded integrator-comb filter) as the first stage for decimation and low-pass filtering, followed by a standard FIR filter as the second stage. This two-stage approach enables backend devices to operate at lower frequencies with reduced hardware costs and power consumption.
Variable Sampling Rate Conversion and Polyphase Filter Implementation
Implementation of variable sampling rate conversion with polyphase filtering. This program demonstrates a complete variable sampling rate conversion pipeline including filter design, interpolation, and decimation processes.
