Logic gates are one of the easiest, highest-scoring, and most important topics for ESE and GATE aspirants from electrical, electronics, instrumentation, computer science, and IT streams. Aspirants can easily score good marks in this topic if they have clear conceptual knowledge. To assist aspirants in their preparation, we explain some basic points of logic gates. This article will help not only competitive exam<\/a> aspirants but also college-going students.<\/div>\n

What are Logic Gates?<\/strong><\/h2>\n

Logic gates are electronic circuits that make logical decisions. Logic gates, in their physical form, are typically found within LSI (Large-Scale Integration) and VLSI (Very Large-Scale Integration) circuits, which also contain many other components. Logic gates allow computers to make logical choices. When using a logic gate, binary numbers (1s and 0s) are used as inputs, and by applying different rules, the logic gate produces an output that is a single number. Every output and input utilized by a logic gate will be one of two different values (False = Low = 0, True = High = 1).<\/p>\n

Logic gates are composed of at least two inputs, with the exception of the NOT gate, which has only one input. A truth table can be created to define the relationship between the inputs of each logic gate and its corresponding output.<\/p>\n

All of the functions performed by a logical gate can be described using Boolean algebra<\/a>.<\/p>\n

Types of Logic Gates<\/strong><\/h2>\n

Logic gates are classified into 3 categories:<\/p>\n
