June 5, 2021 By WatElectronics

This article lists 100+ Logic Gates MCQs for engineering students. All the Logic Gates Questions & Answers given below includes solution and link wherever possible to the relevant topic.

A logic gate is a device it performs logical operations on one or more than one logical input and produces a single output. The inputs for logic gates will be a digital signal and these logic gates perform mathematical operations.

The XNOR, XOR, NOT, NAND, AND, OR, and NOR gates are the basic logic gates. The logic gates can be made from discrete components such as transistors, resistors, and diodes. The RTL, DTL, IIL, TTL, ECL, MOS, and CMOS are seven types of logic families.

The logical gates are categorized into three groups they are basic gates, universal gates, and arithmetic gates. NOT, AND, & OR are basic gates, NAND & NOR are universal gates,  X-OR & X-NOR are athematic gates.

The features of the emitter-coupled logic family are it is the fastest logic family, used in very high-frequency applications, and it has a very large fan-out. Fan-in explains how many inputs can be there with a given logical gate whereas Fan-out explains how many similar gates can be driven by a given logical gate.
