Calculate R and C in Envelope Detector Circuit (AM Modulation)
I think for this problem we are meant to assume w_c and w_m . Very theoretical.

Calculate R and C in Envelope Detector Circuit (AM Modulation)
1. Add impedance in parallel of capacitor and resistor Z_rc = 1/((-wC/j) + 1/R) = (jR)/(j-wRC) 2. Ohm's law for relationship of i_d, Z_rc, and Vo Vo = i_d * (jR)/(j-wRC) Unsure how to do the rest? Thanks.
