1-) Ideal Envelope Detector 2-) AM demodulation using diode and RLC circuit 3-) Demodulation of AM signal using envelope detector Question 9: compare the above demodulation techniques in terms of pros and cons. Which one should be used in practical application and why? Explain.

Analyze the circuit shown below. a. Use the constant voltage drop (CVD) model with 0.7V forward voltage drop to quickly verify that the diode is forward-biased. What is the DC output voltage? What is the DC current through the diode? b. Make a better estimate of the DC output voltage by employing the diode equation (Shockley equation). Assume Iş = 10-14, n= 1, and room temperature (300K). c. Determine the dynamic resistance ra (small-signal resistance) of the diode from the operating point information in part b). Now, consider the case in which a 60HZ sinusoid with 1V peak amplitude is applied [ Vs signal model) to find the AC output voltage due to the sinusoidal component at the supply terminal. What is the resulting total (DC + AC) output voltage at the given DC operating point? 1V-sin(2n-60-t) ]. Use the CVD + resistance diode model (small- 3kQ Vs No 6V
