A periodic rectangular pulse train f(t) shown below has amplitude A = 1 V, pulse width ? = 0.35 ms, and period T0 = 1 ms. The pulse is centered at t = 0.
(a) Find the fundamental frequency f0 of this signal. (b) Find the duty cycle d of this signal. (c) Find the numerical values of a0, and an for 1 ? n ? 5. (d) Plot the one-sided magnitude spectrum for 0 ? f ? 5f0. (e) Plot the one-sided phase spectrum for 0 ? f ? 5f0. (f) Find the expression of approximation ˆ( ) f t consisting of the dc component, the fundamental component, the second harmonic component, and the third harmonic component of its trigonometric Fourier series (sum of cosines). The coefficients must be numbers.
