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 ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...

Electromagnetic energy in the terahertz region of the spectrum – nominally 300 GHz/0.3 THz to 10 THz, although some consider it to start at 100 GHz/0.1 THz – presents a technical dilemma. On one hand, ...

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 ...

AR RF/Microwave Instrumentation launched the FL8000 Series of electric field probes, covering the 5 kHz to 60 GHz frequency range. EMC testing in a lab often requires measuring different types of ...

RFmondial has introduced a broadcast DAB modulator/exciter LV5e module and exhibited it at IBC. The company said the module is designed for enabling transmitter manufacturers to enter the DAB ...

The high oscillation frequencies of light waves make them ideally suited to fast data transmission. They can be sent through optical fibres and easily carry hundreds of billions of bits (Gigabits) per ...
