In the last years, a major transition from analog to digital modulation techniques has occurred and it can be seen in all areas of wireless communication, satellite and cellular systems. This paper ...

An improved F.M. modulator and demodulator are described which are suitable for the transmission of television signals through a field-store standards converter. They represent an improvement on an ...

Imagine for a moment that it's January 2008 and that DVB (The Digital Video Broadcasting Project) is currently drafting a specification called DVB-T2 for the next generation of digital terrestrial ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

The 4K/8K UHDTV satellite broadcasting using ISDB-S3 (Integrated Services Digital Broadcasting for Satellite, 3rd generation), a transmission system researched and developed by NHK STRL, was ...

The master timing control circuit for most electronic applications is a precision signal source. For digital applications, it’s an accurate clock. In RF applications, it’s a carrier source for a ...

This demodulator is suitable for the quadrature phase-shift keying (QPSK) modulator previously published by the same author, "Novel Low-Cost QPSK Modulator Needs No Adjustments" (electronic design, ...

Science & Technology Research Laboratories (STRL) is conducting research on highspeed, high-capacity holographic memory with excellent achievability to enable long-term storage of 8K ultra-high ...

The Audemat FM Modulation Analyzer now features an RF generator to ease the task of commissioning and testing of FM transmitters. Thanks to this combination of features, the Modulation Analyzer, which ...
