could anyone help me to find the frequency and amplitude of this following function:
A*cos(w*t)+ B*sin(x*t)+C*sin(y*t). where A,B,C & w,x,y are three different amplitudes & frequencies respectively.
thnx in advance.
N.B. i am guessing fourier transform should be used. i did a course in intro to signal but i did not quite grasp the concept of the FT. if anyone knew a method besides FT, for example, using trigonometric manipulations i will be really grateful.
