If we replace the potentiometer VR1 with an AC signal plus DC bias signal in any of the previous Figures 3 to 17, the voltage controlled attenuators can become an amplitude modulator circuit instead.

Amplitude modulation (AM) is widely used for not only wireless communications but also sensing and monitoring biomaterials as well as scientific data. Recently analog multipliers are attracting much ...

This article introduces a process framework for debugging quantum circuits, focusing on three distinct types of circuit blocks: amplitude–permutation, phase-modulation, and amplitude–redistribution ...
