The second and concluding volume of Lenk's compilation of information on commonly used electronic circuits features detailed material and data on 700 additional integrated and discrete-component circuits, along with a wealth of new test and troubleshooting data. It explains how circuits operate and where they fit into electronic equipment and systems, and gives a specific troubleshooting approach for each type of circuit. With some 750 illustrations and schematic drawings, the reference supplies proven component values for actual circuits, gives sources and mailing addresses for each, and includes substitution and cross-reference tables to help locate substitute ICs.
