Hi every one , Can you help me build a (8 QAM) Octal Quadratic Amplitude Modulation circuit? I am using NI Multisim 14.1. I have built this circuit for QAM, but the output on the Oscilloscope is incorrect. If you can help me, I will be grateful. https://drive.google.com/file/d/1PGs1MJwKBNiq9CaFbdazPPR3wdP86nG_/view?usp=drive_link
