The goal of the book is to provide basic and advanced knowledge of design, analysis, and circuit implementation for electronic instrumentation and clarify how to get the best out of the analog, digital, and computer circuitry design steps. The reader will learn the physical fundamentals guiding the electrical and mechanical devices that allow for a modern automation and control system, which are widely comprised of computers, electronic instrumentation, communication loops, smart grids, and digital circuitry. It includes practical and technical data on electronic instrumentation with respect to efficiency, maximum power, and applications. Additionally, the text discusses fuzzy logic and neural networks and how they can be used in practice for electronic instrumentation of distributed generation, smart grids, and power systems.

1.1Introduction

This chapter is based on the assumption that the reader is familiar with basic electronics and understanding of analog circuit–based amplifiers. However, even if this is the first time for anyone with regards to this topic, the authors believe that the following sections show how electronics support and are key in the signal conditioning instrumentation design.

In order to start, we can note that electronic amplifiers are used mostly to increase or change the electrical properties of measured signals (voltage, current, impedance, or power). Such signals would hardly be useful to drive functions such as displays, signal processing blocks, or electric drives, and they must be processed by some kind of controller (analog or digital). Specific features such as differential input, feedback, and cancellation of common errors in signal acquisition will make such electronic amplifiers a more suitable device in interfacing electronic circuits or processes, monitored by microcontrollers, or microprocessors or computers. This chapter shows that the differential amplifier is an important system for distortion cancellation of electromagnetic common-mode noises induced in conductors and instrument signal cables, typical of industrial environments [1,2,3].

In order to better understand the nonideal behavior of an instrumentation amplifier, this chapter describes the most relevant aspects of basic electronics in applications that would affect from their operational qualities.
