Essays on Transducers

Introduction

Taking measurements may require the conversion of the measured quantity to electrical quantity. Transducers are devices or elements that perform this function by transforming physical quantities such as quantities like sound, light, or temperature into electrical signals like current, voltage, or capacity. Transducers consist of inputs, sensing elements, transduction elements, signal processing, and electrical outputs. The inputs known as the measurands are the quantities, states, or properties that are to be translated into electrical outputs. The sensing elements accurately measure these input energies and sends the information to the transduction elements to be transformed into the desired form. The ...

Electrical engineering is the largest technological filed in the world. The field offers educational and research opportunities in electronics, photonics, and nanotechnology; sensors, computers, and networking; and communication and control, signal and image processing. Competent electrical engineers have vast expertise in design and development of one or more careers of the discipline: telephone networks and switching systems, receivers and transmitters of radio, television and communication systems, generation and distribution of power, computer systems among others (Chen, 123). Electrical engineers implement, test, install and maintain large-scale electronic devices and machinery used in manufacturing, generation of electric power and transmission. An ...
