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 ...

The National Institute of Information and Communications Technology has successfully developed a highly efficient optical modulator using organic electro-optic polymer (hereinafter referred to as EO ...

Diverse well describes the myriad digital modulation schemes used in modern voice and data communications. The alphabet soup of terminology extends well beyond the familiar QAM and GMSK fundamentals ...

In radio communications, one way to generate single sideband (SSB) signals is to make a double sideband signal by feeding a carrier and a modulation signal into a balanced modulator to create a double ...

Researchers at Skoltech have developed an ultra-compact electro-optic modulator based on silicon photonics and plasmonics ...

Single Sideband, or SSB, has been the predominant amateur radio voice mode for many decades now. It has bee traditionally generated by analogue means, generating a double sideband and filtering away ...

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 ...

Via drilling is a critical process in printed circuit board (PCB) manufacturing, where small holes, known as vias, are created to establish electrical connections between different layers of the board ...
