LOGIC GATES

THE INPUTS OF LOGIC GATES :

many of our security lamps, alarm systems, and washing machines cam make some simple decisions. the switching off operations are controlled by electronic switches made up of logic gates.

look at the electric circuit in a computer, the possible inputs are "on" (1) and "off" (0) inputs. the processor can interpret these inputs and process the information into displays on the monitor. the computer can convert the inputs into every colourful pictures.

TYPE OF LOGIC GATES :

there have five types of logic gates.

A) NOT

B) AND

C) OR

D) NOR

E) NAND

for each gate, the input or inputs are on the left of the symbol. the output is on the right. each output can be either high (logic1) or low (logic 0). a binary "0" represent 0 V and a binary "1" represents a non zero voltage. the name of the gate gives a clue to which input signals are requires before high (logic1) signal is passed to the output.

TRUTH TABLE :

in the learning of logic gates, students should remember this truth table.
