ATLANTA — Eleven leading DSL semiconductor and system vendors used the Supercomm show here to drum up support for discrete multi-tone (DMT) modulation as the line code for very-high-bit-rate digital ...

Another modulation scheme similar to FM is phase modulation. Within the genre of phase modulation, there are many subsets. These schemes lend themselves well to digital uses, and are seen frequently ...

Modulation schemes have different characteristics for different media One of the simplest digital modulation schemes, QAM, takes two subsets of each binary word and applies the magnitude of each ...

Playing both sides of the modulation fence, one chip maker, NxtWave Communications Inc. (Langhorne, Pa.), announced silicon last week that comes in versions for both schemes.

The modulation scheme 16FSK is pretty unusual and not widely used. Yet it is now available in a new IC from CML Microcircuits.

Epsilon-near-zero (ENZ) effect based on the transparent conducting oxides (TCOs) has been emerged as a robust LMI enhancing scheme for all-optical switch, E-O modulation, perfect absorption ...

RF broadcasters at NAB2007 saw two competing ATSC in-band modulation schemes for sending video to mobile devices using the digital TV spectrum.

Anyway, the result with this polar modulation scheme is an efficient PA but with the necessary amplitude components for 3π/8-shifted 8PSK. There are other schemes to produce polar modulation ...

There are two radio modulation schemes everyone should know. Amplitude modulation changes the amplitude — or ‘volume’, if you will — of a carrier frequency and turns all radio into ...
