Here we report a flexible all-graphene modulator circuit with the capability of encoding a carrier signal with quaternary digital information.

It depends on a proposed block, called Constant Amplitude (CA) modulation. The whole characteristic mathematical analysis is presented for the proposed system. Additionally, the complexity evolution ...

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 ...

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.

AM Signal Generation: The modulator inherently generates amplitude modulation (AM) signals. The added frequency components carry the amplitude-modulated information. Efficiency: Square law modulators ...
