Document Summary

Gates: lets examine the processing of the following six types of gates, not, and, or, xor, nand, nor, typically, logic diagrams are black and white, and the gates are distinguished only by their shape. Not gate: a not gate accepts one input value, and produces one output value, by definition, if the input for a not gate is 0, the output value is 1. And gate (multiplication: an and gate accepts two input signals, ex. If the input value for and gate are both 1 the output is 1. If the two input values are both 0, the output value is 0. Nand and nor gates: the nand (not and and combined) and nor (not and or combined) gates are essentially the opposite of the and and or gates, respectively. If the electrical signal is grounded, it is allowed to flow through an alternative route to the ground, where it can do no harm.
