Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

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.

How to quantify the power-supply noise sensitivity of signal-processing chain loads. How to calculate the maximum acceptable power-supply noise. Strategies to meet power-domain sensitivity with ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

Since graphene has a low absorption coefficient in the absorption band, researchers generally use graphene as a carrier collection layer, and look for another strong light-absorbing material as the ...
