Detailed Documentation
This document presents a MATLAB-implemented passive RC and LC filter design system. The system supports the design of four fundamental filter types: Low-Pass (LP), High-Pass (HP), Band-Pass (BP), and Band-Stop (BS) filters. The implementation utilizes MATLAB's signal processing toolbox functions such as butter, cheby1, and ellip for filter coefficient calculation, followed by component value derivation using passive network synthesis techniques. This system proves particularly valuable for noise filtration while preserving essential signal components. Notably, the system incorporates built-in design results visualization through MATLAB's plotting functions (e.g., bode, freqs) for immediate analysis of frequency response characteristics. Through this platform, users can deepen their understanding of passive filter design methodologies and effectively apply them to practical engineering challenges involving analog signal conditioning and interference suppression.
