Application of Signal Processing System in Comprehensive Practice of Electronic Information Engineering

Abstract

Comprehensive electronic information engineering practice serves as a critical bridge between theory and engineering application.
As a core technical tool, the depth of signal processing system implementation directly impacts students 'engineering competency development. This paper elaborates on practical implementation paths for five scenarios: low-frequency signal acquisition calibration, power frequency interference filtering, short-range communication modulation, speech noise reduction optimization, and dual-channel fault simulation.
It specifies hardware configurations (e.g., STM32, ADXL355), algorithm parameters (e.g., IIR filter passband, RLS step size), and operational
verification criteria (e.g., error ?0.5? , 15dB SNR improvement). Through concrete case studies, it addresses the disconnect between simulation and practical implementation, establishing a closed-loop process from hardware development to performance verification. This provides a
reusable solution for practical education, fostering students' engineering problem-solving mindset.
