Homework Statement
How do i find the phase between sine waves knowing the time difference between each?
http://users.bigpond.net.au/exidez/sinewave.jpg
Equation for the main function is 3cos(30t - Pi/2)
The smaller sine wave is of the same frequency when is settles in a steady state.
Homework Equations
i thought it was
time difference * 2*Pi*f = phase difference in radians
The Attempt at a Solution
30 = 2*Pi * f
-.05*30 = 1.5 radians
-1.5*360/(2Pi) = -85.94 degrees
MATLAB give the phase difference as -76.3995 degrees
this is equivalent to -0.0444474274 difference in seconds
Is this just due to rounding error??
