Digital Logic Gates
Work of a logic gate
is to perform a logical operation on
one or more logic inputs and give us
a single logic output. This logic is
called Boolean logic. Logic gates
are generally applied electronically
using transistors or diodes.
In electronic logic, a logic level
is represented by a
voltage or current. Below are
given the gates used in electronics.
The AND gate is a logic gate
that gives an output of '1' only
when all of its inputs are '1'.

The OR gate is a logic gate
that gives an output of '0' only
when all of its inputs are '0'

The
NOT gate
is a logic gate that gives an output
that is opposite the state of its
input.

The
NAND gate
is an AND gate with a NOT gate
at its end

The NOR gate is an OR gate
with a NOT gate at its end.

In XNOR The
output is high when both inputs A
and B are high

In XOR The
output is LOW when both inputs A and
B are high

Now let us see what are capacitors,
resistors, diodes & transistors in
electronics circuits and what are
their applications.
