- Calculate the values for R and C on the envelope detector given below. Explain the role of the diode, resistor, and capacitor on the demodulation of the AM signal.
- Zc = -j/wC, R=V/I
1. Add impedance in parallel of capacitor and resistor
- Z_rc = 1/((-wC/j) + 1/R) = (jR)/(j-wRC)
- Vo = i_d * (jR)/(j-wRC)
