Consider that a pulse train signal leads to have a Fourier Series given by the expression C n = (2/3) sinc (n/3) [V], then: a)

Consider that a pulse train signal leads to have a Fourier Series given by the expression C_n = (2/3π) sinc (n/3) [V], then:

a) Plot the one-sided magnitude and phase spectra, considering six components,  in addition to the DC component. Procedure required
b) Consider that the period of the waveform in time is 250 [ms]. Express, in your  Conjugate phasor representation, the sine component corresponding to the fifth harmonic.  Procedure required
c) Sketch a graph of the waveform over time. Consider the period given in part b.
