carrier wave:

see modulationmodulation,
in communications, process in which some characteristic of a wave (the carrier wave) is made to vary in accordance with an information-bearing signal wave (the modulating wave); demodulation is the process by which the original signal is recovered from the wave

carrier frequency

The transmission of a fixed frequency that has been altered (modulated) to "carry" data. The frequency is measured in Hertz (cycles per second). See carrier, Hz, FDM and TDM.

(2) For the case of V(x') = [alpha]x', the solution of Equation (5) is Equation (39) by Chen and Liu [44-45], which is also composed of a envelope and carrier wave. The mass centre of the particle is at [x.sub.0], which is its localized position.
Next, in contrast to the conventional theoretical approach that uses the single Gaussian pulse as a primary model task, the practical engineering approach is reasonable to develop on the basis of the model task of rectangular pulse with a harmonic carrier wave. This task is explained below in Fig.
We denote the wave vectors of the left- and right-going incident carrier waves as [k.sub.l] and [k.sub.r], respectively; therefore, the wave vector of newly developed carrier wave [k.sub.c] has to satisfy the phase-matching condition: [k.sub.c] ~ [k.sub.n] = [m.sub.l][k.sub.l] + [m.sub.r][k.sub.r] for maximal amplitudes, where [m.sub.l,r] are the integers determined by the order of harmonics.
As Table 5 illustrates, parameters of potential biological significance include the frequency content of the signal (ratio of modulation frequency to carrier wave frequency), the ratio of peak-to-average RF wave amplitude, the central frequency of the RF (carrier wave), and the modulation frequency (typically ~ 0-10 kHz).
Thankfully, I get a let of letters like yours, and I am delighted that, even if the point doesn't hit, the carrier wave at least gives you some entertainment, and also may cause you to look twice at the subliminal messages.
I started to recognize the robots who look human but transmit the medial carrier wave beat frequency that has brainwashed us--for millennia....
Maniacal ambition notwithstanding, the Internet certainly looks like the carrier wave of a marketing revolution.
The L1 signal can be divided into three components: carrier wave, tracking codes, and navigation message.
An RBDS encoder allows a radio station to piggy-back another stream of digital data onto its normal carrier wave. Information such as traffic and weather can be received by RBDS-equipped radios and scrolled across the unit's LCD screen.
In PWM, the carrier wave will be a chaotic carrier wave and the modulating signal remains the same, that is, DC signal.
