Extracted text: Q5. [CO1] In fig, given below the input s (t) = m (t), and the amplitude A>> | s (t) |. The two diodes are identical with resistance r ohms in the conducting mode and infinite resistance in the cut-off mode. Show that output e (t) is given by e(t) = 2R w(t)m(t) r+R where w (t) is switching period sign with period 2n/Wc seconds. a. Hence, show that this circuit can be used as DSB-SC modulator. b. How this circuit can be used as a synchronous demodulator for DSB-SC signal. slope = 1/r s (t) R A coswt id s(t) e (t) vd s (t) R w (t) t. t 2π-π/2 π2 -2n
