A sampling and storage system for arbitrary biomedical waveforms.

This paper describes a microcontroller based system which can sample, monitor and store, and generate biomedical waveforms. The frequency of the output waveform is controllable. The inherent advantage of this system is the programming flexibility offered by the microcontroller. Applications include patient monitoring, test signal generator for repair and maintenance of EEG or ECG monitoring equipment, and a laboratory simulation device for student educational use.
