3. Find the Continuous Time Fourier Series Coefficients of the following periodic signals a) x(t) is periodic with period 6, and is defined over a period as (3X15-45 points) x(t) = 2,0 K 1 1,1 s t<.3 hint: start with the ctfs of rectangular pulse and think how you can convert to x then apply properties. b is periodic period defined over a a:s s t properties c as in this question have reverse. familiar signal. find continuous time fourier series coefficients following signals points k signal>
