Thanks a lot Ravil !
Yes my modulated signal has DC component and I want to remove it but could not find any way to get rid of it.
If it would be an electrical signal than I can use clipper/ clamper to remove Dc component but I don’t know how to remove Dc component in Optical signal.
Dear Ravil after modulation from EAM, I am going to contract this signal but due to DC component I am getting a contracted modulated signal like shown in below attached pic.
If I would transmit such a signal over fiber it will degrade my sys overall performance severely due to collision( as u can see from red portion in graph) and many other factors.
So to get better performance I have to get rid of this DC component. I hope u get my point.
If anyone has solution to this problem kindly share.
Best Regards
