Homework Statement i can find the Fourier coefficient of the signal but i could't understand how to find the frequencies which are present in the signal.can anyone help me?

i have found the same question in my book and i understood my mistake but i could't understand something. book says that the rectangular which is the result of the convolution has a height 1.i don't know how to call it maybe i should say magnitude.but i know that in the Fourier transform if...

i think Wo is 7*pi/2 am i wrong??

ok thank u very much but at last i wanted to make things clear if we look only in one period is it a convolution of a square and two diracs?

i think that convolution of a signal with a delta is again itself but i have a confusion about the transform of cos? is it a dirac at 7*pi/2 and -7*pi/2 with magnitude pi

yes but this question is from an old midterm i don't know if it is also in my book? if it is in the book it would be perfect if u could tell me the question number

oh =) i couldn't see the sinc function but then i think the answer is the convolution of the Fourier transforms of sinc and cos but i can't realize how to take their convolution

and i am sorry for my bad usage of the forum, as you know i am a novice user

i know when signals in multiplication we can take the convolution of their Fourier transforms to find the Fourier transform of the signal but there is a third term 1/pi*n which i don't know how to find its Fourier transform so that confused me

fourier transform simple question?? pls help can anyone help me in finding the Fourier transform of this signal?? i need quick help
