Hey guys,
I've been trying to create an AM modulator on proteus. So I managed to reproduce the circuit using a laplacian filter block (as given in the diagrams). But when I replace the Laplacian blocks with their RC counterparts, I don't get the modulated signal.
Additional details:
Vc is 1MHz. Vm is 1KHz.
R1=3300 C1=33pF
R2=470 C2=470PF
T for HP1 =R1xC1 =220.9ns
T for LP1 =R2xC2 =108.9ns
As shown in the images attached, the circuit works with the Laplacian filter blocks but not the RC filter. What am I doing wrong?
