Question
The diagrams below depict a modulation (left) and a demodulation(right).
(a) Express y(t), u(t) and z (t).
(b) What may happen to the demodulated signal y(t) if there is a phase shift between x(t) and the carrier signal?
(c) How would you qualify the demodulation in the figure 2 above, coherent or incoherent? Justify your answer.
i. Explain the purposes of modulation and demodulation.
ii. Give 2 synonyms in electronics of modulation and demodulation.
