TAILIEUCHUNG - Introduction To Electronic Circuits

Some basic concepts of analogue signals are introduced in this section. You will learn the basic functions of an analogue electronic system, viz. transformation and generation of signals of continuous nature. Here, signal transformation refers to all kinds of manipulation such as filtering (selecting signals of a certain range of frequencies) and amplification (enlarging the magnitude of a signal). Signal generation in the context of analogue electronics can be taken to mean the construction of a signal with a specified waveform, as in the case of a sinusoidal wave generator. This section prepares you for the study. | Ray Powell ARNOLD ESSENTIAL ELECTRONICS INTRODUCTION TO ELECTRIC CIRCUITS First published in Great Britain 1995 by Arnold a member of the Hodder Headline Group. 338 Euston Road London NW1 3BH 1995 Ray Powell All rights reserved.
