sales text:
Design and Development of Medical Electronic Instrumentation fills a
gap in the existing medical electronic devices literature by providing
background and examples of how medical instrumentation is actually
designed and tested. The book includes practical examples and
projects, including working schematics, ranging in difficulty from
simple biopotential amplifiers to computer-controlled defibrillators.
Covering every stage of the development process, the book provides
complete coverage of the practical aspects of amplifying, processing,
simulating and evoking biopotentials. In addition, two chapters
address the issue of safety in the development of electronic medical
devices, and providing valuable insider advice.
Chapter 5 covers data acquisition in detail.
