I'm having a bit of a difficulty trying to determine the fundamental frequency in a given function and the harmonics.
In the equation below,would the fundamental frequention be 1 (corresponding to the value cos(1x-pi)) and the harmonics amplitude 3 and -4?Also,the values of the frequency of the harmonic are equal (both 3),so how would it be represented in the domain frequency?
Considering x=w0t
v(t)=3sin(3x) - 4cos(3x) + cos(x-pi)
cos(x-pi)=cosx (is this right??),so
v(t)=3sin(3x) - 4cos(3x) + cos(x)
Thanks in advance for the reply!
