Problem 3. Determine the trigonometric Fourier series coefficients an and bn for signal a(t) sin(3t 1)2 cos(7t 2) Determine also the signal's fundamental radian frequency w. No integration is required to solve this problem.
Find Fourier series coefficients a0, an, bn and cn (ALL of these coefficients) for the following periodic signals. You can use symmetry to determine whether an or bn is zero – observe carefully. However, you are NOT allowed to extract a0, an and bn from the expression of cn. That is to say, you need to find a0, an and bn exclusively from symmetry or by integration.
