This book is for the student, engineer or technician who understands basic electronics and wants to learn more about electronic measurements. To use instruments effectively, it is necessary to understand basic measurement theory and how it relates to practical measurements. This book explains these fundamentals as well as practical measurement techniques. The book makes extensive use of circuit models or 'black boxes' to explain instrument behavior. This circuit model approach reduces the amount of detail that must be remembered and understood.
AIM To introduce the concept of measurement and the related instrumentation requirement as a vital ingredient of electronics and communication engineering. OBJECTIVE To learn. Basic measurement concepts. Concepts of electronic measurements. Importance of signal generators and signal analysers in measurements. Relevance of digital instruments in measurements. The need for data acquisition systems.
