This book provides a sound introduction to basic electronic concepts in a lively and practical format. It effectively meets the needs of both the electronics option of the advanced GNVQ in engineering and the BTEC National certificate in electronics and includes hands-on practical investigations and self-test questions which will appeal to a wide range of readers. Applied Electronics employs user-friendly text and a non-mathematical approach to develop the reader's ability and understanding of the principles of analogue and digital electronics. Beginning with the semiconductor devices themselves, it progresses through amplifiers and power supplies to combinational and sequential logic.
