Design a circuit for the given canonical form,Draw the circuit
diagram and verify the De-Morgan laws.
AIM: To construct a circuit for the given canonical form, draw the circuit diagram
and verify the De-Morgan laws.
APPARATUS REQUIRED:
COMPONENTS:
1. IC 7408, 7432 and 7404.
EQUIPMENT:
1. Power supply
2. Bread Board.
PROCEDURE:
1. Construct the circuit on breadboard for each Gate as shown in figures by
inserting the appropriate IC.
2. Check the combinations of various inputs as shown in truth tables for each
Gate.
3. If the input is low connect input to Ground, which indicates logic 0.
4. If input is high or logic 1 then connect the input to the power supply.
5.
When output is high the LED will glow which indicates output as high, if the
LED is not glowing then the output is low.
DESCRIPTION:
1. The basic rules and laws of both Boolean Algebra and DeMorgan’s
theorem are used to reduce a given expression to a simplified form so that
the number of gates are minimized to as far as possible to produce the
same output.
2. A Truth Table defines how a combination of gates will react to all possible
input combinations.
3. A Logic Probe is a piece of test equipment which displays the logic level at
a point in the circuit. 0 to 0.8V = Logic 0 and lights the L indicator. 2.0V to
5.0V = Logic 1 and lights the H indicator. Invalid logic voltage levels light
neither indicator.
