A digital circuit is a circuit where the signal must be one of two discrete levels. A digital circuit can be used to rectify noise and produce correct signals. As digital circuits are made up of basic logic gates, they are not very expensive. Switching time is much faster as compared to that of analog circuits. Digital electronic circuits are relatively easy to design. It has higher accuracy, programmability. This book is designed for all the readers who are aspiring to learn the concepts of digital circuits
