[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 ...

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 ...

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 ...

Two separate data streams are generated using clocks at a 90 degree phase shift, and these are passed to the software signal processing for demodulation. But what happens if you lack a pair of ...

He argued that the black foam for a quality control test, a type of short circuit and demodulation used by Apple, aren’t ...

Abstract: Systems, eye-mountable devices, and methods that facilitate chronotherapeutic treatment of primary open-angle ...
