Split combined signals

[isaacvega]

Hello,

I have two combined signals (sine waves) one with a frequency of 2MHz and another one @2.7MHz. I haven't been succesful in finding the proper algorithm to split the combined signal into its two different components. Could anyone give me a push in the right direction?

Thanks!

Are these two signals from separate sources and have been added together in software? Or is it a composite signal with two frequency components?

If the latter, filters may be the solution.

What is the sampling rate? How much do the frequencies vary? What characteristics of each signal are you trying to measure? What format or datatype represents the signals? How many samples are in each data set? Can you post some data along with what you expect the outputs to be?

The signals come from a sig gen each output of the sig gen is run through a combiner the output of the combiner goes to a digitizer, I am capturing 1M samples @ 2.5GS/s.
