Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

Common digital modulation techniques include amplitude-shift keying (ASK), frequency-shift keying (FSK), and phase-shift keying (PSK). ASK is the simplest of these techniques, and is used for low ...

Anyway, along comes a new company MagnaCom with a new modulation method called WAve Modulation (WAM). You won’t find it any textbook and the company won’t reveal any details on how it works.

Phase modulation is weird and almost unheard of, but that doesn’t mean you can’t implement it on an FPGA. [nckm] is transmitting audio using phase modulation on an FPGA (Russian, here’s the ...
