Truth Tables In Boolean algebra, truth table is a table showing the truth value of a statement formula for each possible combination of truth values of component statements. A statement is a declarative sentence which has one and only one of the two possible values called truth values. Truth values are true and false, denoted by the symbols T and F, respectively, and they are also denoted by symbols 1 and 0. Since we allow only two possible truth values, this logic is called two-valued logic ... Truth table, in logic, chart that shows the truth-value of one or more compound propositions for every possible combination of truth-values of the propositions making up the compound ones. It can be used to test the validity of arguments. Every proposition is assumed to be either true or false and Figure-2:Truth Table of AND Gate A simple 2-input logic AND gate can be constructed using RTL (Resistor-Transistor-Logic) switches connected together as shown below with the inputs connected directly to the transistor bases. Logic Gates are defined as digital circuits that operates on one or more digital inputs and produces an one output signal. Logic gates are called digital
