can anyone suggest me how to remove noise which have same value of frequency like my source in optisystem . my source is LED and my noise is White light LED and both have same frequency so plz suggest me how to remove it in optisystem.

Hello Vikram,
typically, noise exist within the signal bandwidth. The best way to minimize the noise in any signal is to use optical bandpass filter. Depending on the design, users setup the filter bandwidth. There are other schemes that can be used. However the choice depends on the application.
I hope this helps.

Yes I’m using rectangular filter in one case but it works only when signal freq and noise freq are different otherwise it will block noise as well as signal also in case of same freq.
So I want if two signal having same freq how one can pass one signal and block 2nd one in optisystem.
