HALF
ADDER
Hello
friends today we are going to learn what is a half adder? & how they work,
To make my post Even more interesting I used simulation software such as
LABVIEW, PSpice, NI Multisim etc. These simulation software provides a
realistic environment and it make learning Even more interesting.
HALF ADDER
v A Half
Adder adds two one bit binary number.
v A binary
number is understood by machines. And they have only two symbol 0 (zero) &
1 (one).
v Have a look
at this table which shows the binary equivalent of decimal number. (4 bit
binary number).
v To perform
addition using half adder, use 2 one bit binary numbers.
A & B
A & B
v Before
performing our addition program let’s do it manually.
binary addition is similar to that of normal decimal addition
when A and B are zero we get zero, when A is zero and B is one the output is 1, but in case when both A and B is 1 the output is 1 0 but for decimal addition it is 2 .

A 0 0
1
B 0
1 1 2

1 1
0 1 0
LabView – for labview simulation I used one AND gate, one EX-OR
gate along with controls and indicator.
In front pannel window i used AND & EX-OR gate to design a half adder circuit.
PSpice – for PSpice I used AND and EX-OR gate from components
library and connected with there respective devices.
NI Multisim – for Multisim I used
AND and EX-OR gate from components library and connected to respective devices.
Additionally I connected a CRO
which allowed me to visualize the waveform, These is a HIGH and LOW signal which determine ON and OFF
condition of gates.
MATLAB – In MATLAB I used
Simulink model and AND & XOR gate to perform our logical operation.
You can download simulation files you can also make use of truth table to
have a better understanding. I have also added a power point presentation which
you can download.
