Logic Gates are circuits made up of transistors, diodes,
and resistors. Logic gates process one or more input signals in a logical
fashion. Depending on the input value or voltage, the logic gate will
either output a value of '1' for ON or a value of '0' for OFF.
Gates allow simplification of circuit operation. A basic understanding
of logic gates will aid technicians in electrical diagnosis.
five common logic gates used in wiring diagrams are the:
AND, OR, NOT, NAND, NOR
