Script from the year 2015 in the subject Physics - Applied physics, , language: English, abstract: This book is written for understanding the basic concepts of logic gates and Boolean algebra that comes in Senior/Higher secondary classes. The students of these classes are not familiar with the symbols and logical operation of various basic building blocks of a digital circuit. There are plenty of instruments used in daily life that are based on the digital principles so the knowledge of these building blocks helps a lot to understand the working of these devices.
