[brmarcum] takes us back to analog building block basics with his Frequency Modulation and Demodulation tutorial. Frequency Modulation (FM) sounds simple at first, but understanding the electronics ...

This article investigates the demodulation capabilities of a DSSSsuper-regenerative receiver. Starting from the general expressionthat characterizes the receiver's behavior, we demonstrate that afew ...

Trace gas sensors are used in different fields. Light-induced thermoelastic spectroscopy (LITES) has extremely high sensitivity and offers non-contact measurement, attracting extensive research ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

The theoretical and practical requirements for introducing synchronous demodulation into domestic receivers for MF/LF broadcasting are discussed. The difficulties encountered in the construction and ...

Current extrinsic fiber acoustic sensors face two primary challenges. The first lies in the time-varying initial phase of the interference signal, which arises from environmental vibrations, ...

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 ...
