AM simulation

[hcam]

Hi Mr.Tayyab,

I already asked you several days ago (Reference#1948659), I still cannot simulate the attached schematic. If you take out the AGC block, you will see that at the scope after the R18 a sine wave of 10kHz. However, if we leave the AGC block as shown in the schematic, we cannot get anything coming out from R18 which is not right. I cannot see anything wrong with this. Could someone give me an idea? Individual block works perfectly.

Thank you.

Hi,

The reason there is a problem is because you have another VSS in the AGC block which has the value set to 2.5V. I changed the name of that Voltage source and now the simulation is providing the results as expected.

Hope this helps.

You're perfectly right. What is the most difficult thing to simulate in Multisim or that gave you some trouble in simulation?

Thank you.
