And building this one-transistor transmitter is just ... although it can be modified for amplitude modulation (AM) voice work. The circuit is flexible enough that almost any part can be ...

But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation ... Those go to a circuit board he designed which ...

Importantly, the ambipolarity of graphene transistors drastically reduces the circuit complexity ... into quaternary digital modulation schemes such as quaternary amplitude-shift keying (4-ASK ...

A new technical paper titled “Three-to-one analog signal modulation with a single back-bias-controlled reconfigurable transistor” was published ... of the new variant can be exploited for analog ...

The frequency range was limited by the bandwidth of the detector employed in the measurements, not by the transistor device. "In addition to the usual current-modulation capability, the tunnel ...
