In this book we have included more examples, tutorial problems and objective test questions in almost all the chapters.The chapter on Optoelectronic Devices has been expanded to include more application examples in the area of optical fibre networks.The chapter on Regulated Power Supply carries more detailed study of fixed positive-Fixed negative and adjustable-linear IC voltage regulators as well as swithching voltage regulator.The topic on OP-AMPs has been separated from the chapter on integrated Circuits.A new chapter is prepard on OP-AMPs and its Applications.The Chapter on OP-AMPs and its Applications includes OP-AMP based Oscillator circuits, active filters etc.The circuit efficiency of a class-A amplifier can be increased by using (a) low dc power input (b) direct-coupled load (0) low-rating ... (a) 78.5 (b) 25 (c) 50 (d) 85 A transistor audio amplifier is found to have an overall efficiency of 70 per cent.
