Document Summary

Gate- a device that performs a basic operation on electrical signals, accepting one or more input signals and producing a single output signal. Circuits: a combination of interacting gates designed to accomplish a specific logical function. Boolean algebra: a mathematical notation for expressing two-valued logical function. Logic diagram: a graphical representation of a circuit; each type of gate has its own symbol. Truth table: a table showing all possible input values and the associated output values. Not typically, logic diagrams are black and white with gates distinguished only by their shape. Not gate- accepts one input signal (0 or 1) and returns the opposite signal as output. And gate- accepts 2 input signals, if both are 1, the output is 1; otherwise, the output is 0. Or gate -accepts two input signals, if both are 0, the output is 0; otherwise, the output is 1.
