Automated impedence: a case study in microprocessor programming.

Abstract An automated system for measuring biological impedances is described. A microcomputer system is utilized for experimental control, data acquisition, and data reduction. The developed software uses high-level languages and the ability to mix subroutines written in different languages, which are available for microcomputer systems. The software control of analog-to-digital and digital-to-analog conversions is also discussed. The pitfalls, as well as the advantages, of employing a microcomputer system in a task-dedicated laboratory system are presented.
