[Craig] thought it would be fun to build an analog BPSK31 demodulator and hit upon the idea of doing this with amplitude demodulation. No, this isn’t the way you’re supposed to do it ...

A novel acoustic attack named 'PIXHELL' can leak secrets from air-gapped and audio-gapped systems, and without requiring ...

Bandpass modulation techniques encode information as the amplitude, frequency, phase, or phase and amplitude of a sinusoidal carrier. These bandpass modulation schemes are known by their acronyms ASK ...

Rather than demodulating the radio signal with an envelope detector a SSB receiver down-converts the IF one more time using a second frequency mixer to the audio frequency range (this second mixer ...

Baseband modulation techniques encode information directly as the amplitude, width, or position of a pulse. They do not utilize a sinusoidal carrier. Some of these modulation schemes are known by the ...

Now, in 2024, the UCSD research team has finally devised a complex obfuscation technique to foil the Bluetooth “user tracking ...

VOCAL’s facsimile/fax lawful interception software library provides fax demodulation software for image extraction and decoding from intercepted PSTN audio signals. It allows interception, monitoring, ...

The sensing signal is extracted mainly through wavelength demodulation and intensity demodulation. Wavelength demodulation by tracking the movement of resonant wavelength is mainly used in WGM ...

It can be further linked with signal modulation and demodulation devices to achieve the transmission relay of real images, and exhibits great application potential in ultra-high capacity ...

With the proof-of-concept for a system for 6G wireless data transmission based on a photonic THz communications link, Rohde & ...

Keysight Technologies will showcase a range of solutions that accelerate radio frequency (RF) and millimeter wave innovation. Keysight's comprehensive solutions address test challenges with ...
