Basic Electrical & Electronics Engineering (BT-104)
EXPERIMENT NO. 10
OBJECTIVE:
Study and verify truth table for various Logic Gates like AND, OR, NAND, NOR, EXOR and
EXNOR gates, using trainer kit.
APPARATUS REQUIRED:
Logic trainer kit, Connecting wires.
THEORY:
In digital electronics a gate is a logic circuit with one a more input signal occur for certain
combination of input signal. Gates are digital (two states) circuits because the input & output signal are
either low are high voltage gates are often called logic because they can be analyzed with Boolean Algebra.
NOT GATE:
Also called inverter, an inverter is a gate with one input signal the output is always the
opposite of input state logic symbol.
S.No. INPUT OUTPUT
1 0 1
2 1 0
AND GATE:
The output signal is high only when all input are high, if A & B are input then output Y can
be written as
INPUT OUTPUT
S.No.
A B Y
1 0 0 0
2 0 1 0
3 1 0 0
4 1 1 1
