Development of Low-Cost Data Acquisition Hardware as an Undergraduate Capstone Senior Design Project

This paper discusses a capstone senior design project involving development of a data acquisition system for gaining understanding of digital signal processing at the level of hardware architecture. The Pentium II PC-based design includes a microphone with corresponding conditioning circuitry, an analog-to-digital converter, an 8255 peripheral interface adapter, a MATLAB1 interface, a digital-to-analog converter, and speaker
