And Gate Truth Table. The truth table is used to show the logic gate function. Truth tables, as illustrated in figure 11, are tools designed to help solve this problem.

A truth table has a column for the input of each gate and column for the output of each gate.

You can compare the outputs of different gates. Logic gates are takes some time delay to produce output from input. From nand gate truth table, it can be concluded that the output will be logical 0 or low when all inputs are at logical 1 or high. What do you mean by the truth table of a logic gate? The truth table displays the logical operations on input signals in a table format. In computers, we take input as 0 or 1 while in physics, it is on or off. Hence in digital circuits, nand gate is called as a digital building block. If you don't know about the logic gates and their truth tables and need guidance on them, please go through the following infographic that gives an overview of. The logical diagram and the truth table for the two input nand gate. In order for the output to be high both inputs a and b should be high otherwise the output would be low. Truth table of a 3 switches logic and gate.
