BPSK31 is an extremely popular mode for amateur radio operators; it’s efficient and has a narrow bandwidth and can be implemented with a computer sound card or an Arduino. Just like it says on the tin ...

Many serious machine problems can be diagnosed early with normal vibration analysis techniques based on fast Fourier transforms. But some problems remain dangerously hidden in the vibration reading — ...

[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 ...

Saankhya Labs, a fabless chip startup based here, has announced its Universal TV demodulator IC based on Software Defined Radio (SDR) architecture, and targeted at World TV and PC-TV receiver markets.

WE have examined further the anomalous fluctuations in the superconducting bolometers previously reported by Andrews, Milton and Desorbo 1, and find that, in part, such fluctuations are due to the ...

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 ...

Santa Rosa, CA. Keysight Technologies announced new enhancements for its FieldFox handheld RF and microwave analyzers. FieldFox analyzers now connect to Keysight’s 89600 VSA software for signal ...

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 ...
