An eight bit data acquisition system

This report fully describes a data acquisition system built as a graduate project. The system is primarily intended for digital audio applications and has a nominal sampling rate of 50 kHz. The system is built on three boards, each board is independent of the other so they can be used as separate units, if desired. The sampling rate can be programmed using switches on the board, thus providing a degree of flexibility. Besides digital audio applications, the system could be useful for classroom demonstrations of sampling theory and digital filter theory.
