In the world of information security, much thought goes into ensuring that no information can leave computer networks without ...

By using a binary frequency shift keying (B-FSK), the audio signal frequencies can be modulated to represent binary data, aka ones and zeroes. A frequency of 18.5 kHz represents "0," while 19.5 ...

The performance of frequency-hopping systems with multiple frequency-shift keying and hard decisions is determined for operation against optimal partial-band jamming. A receiver that eliminates the ...

Better utilizing the resources available to us is one of technology’s greatest strengths. Whether it's getting more corn out ...

A frequency-shift keying (FSK) receiver for downlink data transfer through the inductive power link is presented for biomedical implants in this work. Inspired by the design in [1], the proposed ...

A person's capacity for attention has a profound impact on what they see, dictating which details they glean from the world ...

The integration of microwave photonics into sensor and radar systems has emerged as a transformative approach to achieve high-precision measurements of Doppler frequency shift (DFS) and angle-of ...

Magnetic Group forecasts a pivotal shift in the aircraft engine market, with key trends signaling an approaching inflection ...

Advances in technology to support AI and edge computing will likely drive a shift away from quartz timing toward silicon MEMS and precision timing.

To be fair, this is more of a fun toy than an elite exploit, because it involves a web interface that encodes text as ultrasonic frequency shift keying.
