Light Publishing Center, Changchun Institute of Optics, Fine Mechanics And Physics, CAS Complex modulation of optical fields (i.e., the control of light’s amplitude and phase) is vital to the ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

Researchers have made a major advance in quantum computing with a new device that is nearly 100 times smaller than the ...

A new chip-scale device offers unprecedented control over laser frequencies, a key ingredient for large-scale quantum computing. Researchers have achieved an important step forward in quantum ...

Scientists in the Emirates have conceived a new space vector pulse width modulation method that reportedly reduces switching losses and increase efficiency in three-phase photovoltaic inverters. The ...

A look at the simplest FM demodulation technique. It doesn’t give the lowest possible output distortion, it doesn’t reject amplitude distortion effects, but it is simple and can be used at virtually ...

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...

Non-terrestrial networks, combined with early 6G research, demand test equipment capable of handling extreme parameters and ...
