Logic Gates
A digital logic gate is an Integrated Circuit (IC) device that
makes logical decisions based on various combinations of
digital signals presented to it’s inputs.
Digital logic gates can have more than one input signal,
but generally have a single output signal, just like the
decision box on the previous slide.
In the following slides, the input digital signals will be
represented by A and/or B and the output digital signal
will be represented by Q.
The next six slides will demonstrate how the output
digital signal is determined by the input digital signals for
various different digital logic gates (NOT gate, AND gate,
OR gate, NAND gate, NOR gate, XOR gate).
Almost all modern electronics such as computers and cellphones use digital logic circuitry
