Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

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 ...

The efficiency of wireless charging systems is limited by power loss occurring due to frequency changes in the resonant circuits that enable power transfer. These necessary modulations reduce ...

Impressively, the unit registered the lowest frequency loss of any chip to date. Specifically, the engineers noted that the new chip was 15x more stable and 100x more efficient in terms of microwave ...

Fig 1. This shows the spectra of both waveforms when the Class D output is issuing silence (no audio, duty cycle = 50%) with a switching frequency of 333 kHz. Fig 2. The blue line shows the energy ...
