Document Summary

Gate device that performs basic operation on electrical signals, accepting one or more input signals and producing single output signal. Circuit combination of interacting gates designed to accomplish speciic logical function. Boolean algebra mathematical notation for expressing two-valued logical functions; elegant and power way to demonstrate activity of electrical circuits. Logic diagram graphical representation of circuit; each type of gate has its own symbol. Truth table table showing all possible input values and associated output values. Accepts one input value and produces one output value. Xor gate and or gate difer only in input situation. All input must be 1 for output to be 1. At least 1 input must be 1 for output to be. 1 and only 1 input must be 1 for input to be. Transistors device that acts either as wire (conducts electricity) or resistor (blocks low of electricity), depending on voltage level of input signal. Transistor has no moving parts, yet acts like a switch.
