The trigonometric Fourier series of a certain periodic signal is given by
a. Sketch the exponential Fourier spectra.
b. By inspection of the spectra in part (a), sketch the trigonometric Fourier spectra for x(t). Find the compact trigonometric Fourier series from these spectra.
c. Show that the trigonometric series found in part (b) is equivalent to the exponential series for x(t).
d. Find the signal bandwidth.
