In modern communication systems, modulation is a key function that embeds the baseband signal (information) into a carrier wave so that it can be successfully broadcasted through a medium such as ...

The output frequency can vary as much 10 MHz on each side. The output level of the modulator is -5 dBm. In this fm modulator prototype the varactor bias was 7.5V for the best linearity but this could ...

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.

Liu's second research topic is related to the driver-modulator interface in 3-D wafer-scale integration. Currently, most photonic modulators require a DC bias to operate at their optimum.

Isolated amplifiers and isolated modulators allow noisy, high-voltage circuits performing their function to connect to the quiet low-voltage circuits in charge of monitoring and controlling.

Their discovery follows the team’s demonstration last summer of an integrated circuit — an assembly of transistors that is the building block for all electronic devices — capable of working at 1.5 ...

(Image credit: Crazy Tube Circuits) The modulation algorithms move from the original Sidekick's two to three here are inspired by Boss 's '80s benchmark effects – there's an Ensemble one to capture to ...

Thermal circuits: modulation of heat flow by means of electric fields The local thermal conductivity in certain oxides can be precisely defined by a voltage-biased AFM tip, a new CiQUS study shows ...
