Use Fourier properties to find the inverse Fourier transform of the fol- lowing Fourier transforms. Hint: Express the transforms using partial fractions expansions. A calculus book would be a better reference than the course text. (a) 3z 2 - X[z] = 2 +52 +ổ x²+5z+6' where z = eju (b) 8-1 = s² X(s) 2+3s+2' where s = jw.
