I have just started taking signal & systems lessons and here is my question:
If we say that
x0(t) = A.cos(w0t). (a cosine signal with zero phase shift, w0 radian frequency) And if we would like to time-shift this signal by for example
The resulting phase shift should be found by
-w0*t1 = phi. (phi denoting phase shift).
By this logic, if I wanted to find the phase-shift for this signal:
x(t) = sin(pi/4*t-pi/4)
What would the result be? Can I apply the first formula for phase for already phase shifted signals? Or am I missing something very big here? :)
Thank you very much for any kind of help.
