Tektronix, Inc. announced a new software option for its OM4000 optical modulation analyzer series that offers automated test support for 400G multi-carrier coherent optical modulation. This software ...

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 distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...

Fiber-optic interferometric sensors have emerged as essential tools in precision measurement, utilising the interference of coherent light to detect minute displacements and variations in physical ...

Belar Electronics has unveiled its latest innovations for analog and digital AM modulation, as the RF monitoring firm has completed its updates for its legacy AMMA-2. The company says this allows for ...

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 AMMA-2, the new digital AM modulation monitor from Belar, may look like an ordinary piece of broadcast equipment. It’s one rack unit tall and has the typical buttons and LEDs on the front panel.

We’ve been loving the variety of entries to the 2025 One-Hertz Challenge. Many a clock has been entered, to be sure, but also some projects that step well outside simple timekeeping. Case in point, ...
