Hi,
I'm taking a signals and systems class this semester and one of the problems that I am currently working on is:
x(t) = sin(2t) - sin(2t-.1)
I know that you can compute the power of this waveform by multiplying the integral of the square of x(t) by 1/T. However, I also know that wave forms of differing frequency usually just add by using the A^2/2 method. Is there a similar formula for this instance? I don't feel like computing the integral for the square of x(t) is actually what we are supposed to glean from this coursework.
Is there a general case where the sine waves have only a phase difference (as above) and the same frequency?
Thank you for any assistance,
Brad
