An Introduction to Biomedical Instrumentation presents a course of study and applications covering the basic principles of medical and biological instrumentation, as well as the typical features of its design and construction.
The book aims to aid not only the cognitive domain of the readers, but also their psychomotor domain as well. Aside from the seminar topics provided, which are divided into 27 chapters, the book complements these topics with practical applications of the discussions. Figures and mathematical formulas are also given. Major topics discussed include the construction, handling, and utilization of the instruments; current, voltage, resistance, and meters; diodes and transistors; power supply; and storage and processing of data.
The text will be invaluable to medical electronics students who need a reference material to help them learn how to use competently and confidently the equipment that are important in their field.
