Analog transmission is not particularly efficient. When the signal-to-noise ratio of an analog signal deteriorates due to attenuation, amplifying the signal also amplifies noise. Digital signals are ...

The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

A new waveform technology developed by Rockwell Collins in collaboration with the Office of Naval Research and Naval Air Systems Command increases the data rate of information that can be transmitted ...

Curtiss-Wright’s E-SOQPSK (Extensible SOQPSK) is a software-configurable, ultra-low-power Wi-Fi modulation scheme. Its waveforms offer some beneficial performance attributes for aeronautical telemetry ...

Download this article in PDF format. We also want to recognize Rick Gentile of MathWorks as a co-author of this article. Modulation identification is an important function for an intelligent receiver.

The 8-channel neural stimulation chip includes a waveform generator, high voltage output stage, and charge balancer, tested using electrode model, PBS solution, and animal, respectively. The chip ...
