2 Its carrier wave is a kind of the bearing's inherent vibration with high frequency, and its modulating wave is a pass vibration corresponding to the local defect.
3 To extract ( information ) from a modulated carrier wave.
4 The power of the modulated carrier wave is increased by the RF power amplifier.
5 As an orthogonal multi carrier wave system, the OFDM communication system usually leads to a high ratio of peak to mean power, thus greatly decreases the communication quality.
6 The conversion of a modulated carrier wave into a current equivalent to the original signal.
7 This system use electric power carrier wave communication chips, the channels between which are changed to telephone lines,[www.] to realize the long-distance communication of data.
8 In communications, the amplitude variations of an amplitude modulated carrier wave.
9 As each spacecraft orbits the Earth it emits a carrier wave.
10 The test result indicates that the phase modulator without transformer can suppress the carrier wave.
11 Its vibrating end would amplify the signal, and its field-emission property of built-in rectification would separate (or demodulate) the carrier wave from the informational wave.

18 The results indicate that the flicker noise increases while the carrier wave amplitude increases.
19 The key of the infrared sending program was calling the interrupt subroutine to produce the carrier wave and modulate it with the key signal.
20 Because a continuous signal can be propagated farther than a random signal, most long-distance communication systems transmit a continuous carrier wave, which is then modulated to convey data.
