Normalized Autocorrelation of two signals

  1. Aug 11, 2016 #1
    1. The problem statement, all variables and given/known data
    I obtain Autocorrelation function of two signal:

    2. Relevant equations



    3. The attempt at a solution

    I want to know what is Normalized Autocorrelation of above equation?

    Thanks

    Sorry if this is a dumb question, but how can you form an autocorrelation between different functions? Can you show your detailed work?

    Probably a signal comprised of 2 sinusoidal components.

    I used https://en.wikipedia.org/wiki/Autocorrelation on a period of (2pi)
    I found out my answer. when we want to normalized our autocorrelation function we should pay attention to Rx(at t=0)=1 to scale the function.
