Shown in Fig. P-3.6 is a spectrum plot for the periodic signal . The frequency axis has units of rad/s.

a. Determine the fundamental frequency $${?}_0$$ of this signal. b. Determine the (fundamental) period $$T_0$$ of $$x(t)$$, which is the shortest possible period. c. Determine the DC value of this signal. d. A periodic signal of this type can be represented as a Fourier series of the form $$x(t)=\underset{k=??}{\overset{?}{?}}{a}_k{e}^{j{?}_{0}kt}$$ If the Fourier series coefficients of $$x(t)$$ are denoted by $$ak,k=0,\pm 1,\pm 2,\pm 3,\dots$$, determine which coefficients are nonzero. List these nonzero Fourier series coefficients and their values in a table.
