amplitude demodulation; carrier amplitude;the Modulation Depth???????

[torry]

Can anyone help me check whether my vi is correct or not? I didn't get the desired results:the Modulation Depth(%) =0.3, the amplitude of Rx singal =0.3, when I send the Tx singal(the Modulation Depth(%) =0.3).
I didn't know whether the carrier amplitude through MT Demodulate AM VI is correct or not? Or get the carrier amplitude from other method.

Please tell me how can I modify it!
Thank you!

Why aren't equal in the amplitude of Tx and Rx signal????
