Neil Storey's book is unique in providing a 'top-down' approach to electronics, starting with overall concepts and gradually looking at increasing levels of detail. The text provides electrical engineering students with a coherent and comprehensive set of material suitable for introductory courses in analogue and digital design. For non-majors it covers most of the electronics material they will need, providing an understanding of the design, operation and use of electronic circuits.The most significant improvement in this new edition is the use of circuit simulation software as a tool for learning. Students often have difficulty in conceptualising electronic circuits and simulation tools aid understanding both by visualising systems and by reducing the need to perform complex mathematical analysis. PSpice is the most widely used simulation package in academia as well as the industry standard and there are accompanying files that run within PSpice available on ftp://ftp.awl.co.uk/pub/awl-he/engineering/storey/electronics/download.htm A wealth of computer-based exercises suitable for all circuit-simulation software packages. Freely available online PSpice files containing numerous simulations. A new section on programmable logic devices (PLDs). New material on the important topic of electromagnetic compatibility. A new section on laboratory instruments describing oscilloscopes and digital multimeters. A new appendix covering the IEC 617 symbols for logic elements. Even more worked examples and self-assessment exercises.
