The first chapters explain the characteristics of pulse waveforms and RC circuits that must be understood before the study of pulse circuitry can commence. The operation of diodes, BJTs, FETs, and op-amps in switching circuits is covered next and leads to the design and analysis of inverters, Schmitt trigger circuits, multivibrators, IC timer circuits, ramp generators, and function generators. Logic gates, logic circuits, and IC logic families are also explained. After individual circuits and gates are studied, they are used as building blocks to explain digital counting, digital frequency meters, ADCs and DACs, pulse modulation, time division multiplexing. Many design and analysis examples are offered throughout the text. The circuit design approach is a simple step-by-step procedure. Device data sheets in the appendices are referred to, and standard-value components are selected.
