For the differentiator system found in Ex. 6.21, the input is xc(t) = sinc(Bt/π), where B = 10000π, and the sampling interval is T = 10⁻⁴. Sketch the signals and the corresponding spectra at (a) the input of the C/D converter, (b) the input of H(Ω), (c) the output of H(Ω), and (d) the output of the D/C converter. Is the system doing what is expected of it? Explain.
