HI ALL..
AS WE ALL KNOW THE FOLLOWING LOGICAL EXPRESSIONS:
A XOR B= C
C XOR B= A
I HAVE TRIED TO OBTAIN A AFTER CONNECTING TWO XOR (OPTICAL XOR DESIGNED USING SOA)IN SERIES WITH APPROPRIATE INPUTS AS SHOWN IN ATTACHMENT. BUT I AM NOT GETTING CORRECT VALUE OF A.HOWEVER I AM ABLE TO GET OUPTUT C (FIRST EQUATION OUTPUT)WHICH IS IS EXACT VALUE OF A XOR B (CAN BE SEEN IN OSCILLOSCOPE) .CAN ANY BODY POINT OUT THE ERROR.
WAITING FOR RESPONSE EAGERLY….
The reason why this is happening is because the C signal is experiencing a delay. Look at the attached pic and you will see that the RED signal is delayed by 3 bit periods. If you introduce a time delay in the second signal the output should be resolved. (Use the Time Delay component in the Passives library).
THANKS DAMIAN FOR YOUR HELP.YOU GUYS ARE DOING GREAT JOB!!!!
Hi Damian,
From the attached image i found that C signl(red line) is delayed by 5 bit periods w.r.t origin,and another signal B is delayed by 3 bit periods. So delay between them is 2 bit periods.
I got correct output when i run the simulation with 2 bit periods delay.
I am attaching my output image.
If i am wrong please rectify me.
YA SIVA U ARE RIGHT.CAN U ATTACH THE PROJECT FILE WITH CORRECT DELAY FOR ME PLEASE.
Hi vipul,
just add time delay element after optical gaussian pulse generator( in B signal) and set delay as 2 bit periods means 2*(1/Bit rate).
Please see the attached image.
