I am lost for last 4 hours
yes i know euler identity is going to be used
i have solved 10 other questions which were in the form of cosine and sine
but i am stuck with this one
I think I must be missing something, but what that signal looks like to me is a composite of 20 signals (first through 10th harmonic) (K=-10 to +10) Maybe the answer is 3? (All the other frequencies are harmonics of that)
