How can I separate a signal of same frequency but different amplitude?

I am trying to find out a way to split a signal of same frequency but having different amplitude at different time stamp. Attached is the sample data signal. If anyone has any idea how to do that please let me know.

Thank you, Akshay

Have you tried looking at the Fourier transformn of your signal to verify your hypothesis?

Thank you Jose-Luis, Yes, I have tried with FFT method, but not able to split into two signals since we will get single discrete response for entire signal.

From your image, it looks like you have alternating signals, not the sum if two signals. That's quite different.

The fft signal for the amplitude should be the same but don't you see a difference (two spikes) in the phase signal?

I tried that but its not working, i mean not able to separate it.

@Akshay Ratnaparkhe: Please post the code you have tried and explain, what "not working" means. For helping you it is necessary to know any details.

The signal samples in the image looks like they are time-domain multiplexed.Try this x1 = x(1:2:end) and x2 = x(2:2:end). Don't know if that is what you need, but give it a try, I mean try taking FFTs of x1 and x2 later to see if the frequencies match (mismatch in 2 or 3 fft bins would be fine). Just curious, is it an output to test a possible jitter in your signal?
