There have been many advances in electronics since the publication of the first edition of Dr Jones' highly successful introduction to electronic circuits. This is reflected in two completely new chapters on digital techniques and computers which present in an easily digestible form the important relationship of the microcomputer chip to other circuits. In the remainder of the book many detailed, changes have updated it without destroying the original logical structure. The book remains a full account of the subject, starting with basic concepts such as amplification and progressing to analogue and digital IC chip applications.
