Tutorial21: Dynamic AM demodulation by LINE IN/OUT
You need to download DSPLinks (v1.60~) and install it on your PC.

After you complete this tutorial, you have this schematic.

Please move NOTCH out of the circuit.

Click on "Parts" icon (transistor mark).

If you click anywhere in the schematic, you will have "Parts Select" dialog. Then choose FUNCABS, that is to take absolute value of the signal.
