Electronics engineering is a sub-discipline of electrical engineering which makes use of nonlinear and active electrical devices like transistors and diodes for designing electronic circuits and systems. Integrated circuits and printed circuit boards are also important parts of this discipline. Electronics engineering can be further classified into various sub-fields such as solid state physics, telecommunications engineering, signal processing, systems engineering, robotics, VLSI design and instrumentation engineering. Electronic circuits can be divided into analog and digital circuits. Analog circuits include amplifiers, oscillators, function generators, and wave shaping circuits. Multiplexers, decoders and microprocessors are some prominent examples of digital circuits. Electronics engineering finds extensive applications across various fields such as consumer electronics, industrial automation and aerospace industry. Some of the emerging areas of research under this field are image processing, motion control and smart grid systems. This book unfolds the innovative aspects of electronics engineering which will be crucial for the holistic understanding of the subject matter. Some of the diverse topics covered herein address the varied branches that fall under this category. Those in search of information to further their knowledge will be greatly assisted by this book.
