The book covers The complete syllabus of subject as suggested by most of The universities in India. Proper balance between mathematical details and qualitative discussion. Subject matter in Each Chapter develops systematically from inception. Large number of carefully selected worked examples in sufficient details. Each Chapter of The book is saturated with much needed test supported by neat and self-explanatory diagrams to make The subject self-speaking to a great extent. No other reference is required. Ideally suited for self-study. table of content1 - number System and codes2 - Boolean Algebra and minimization techniques - logic gates4 - logic families - Arithmetic Circuits6 - Combinational circuits7 - flip-flops8 - counters9 - registers10 - memory and programmable logic devices11 - synchronous sequential circuits12 - asynchronous sequential Circuits13 - bred/a and a/Brad converters14 - clock generators - applications of digital Circuits16 - HDL for digital circuits appendix lab work and viva-voice questions.
