例句 | Here a carrier wave having the basic frequency of the radio station, perhaps 105.1 MHz, is modulated in frequency by the audio signal, producing a wave of constant amplitude but varying frequency. College Physics for AP Courses 2015-08-12T00:00:00Z The researchers couple their resonating circuit to a second, higher frequency circuit, so that, much as in AM radio, any dark matter signal would make the amplitude of the higher frequency carrier wave warble. To crack the mystery of dark matter, physicists turn to supersensitive quantum sensors 2022-04-27T04:00:00Z The FCC’s RFR exposure limits regulate the intensity of exposure, taking into account the frequency of the carrier waves, but ignore the signaling properties of the RFR.

The Techno-Signature Challenge 2018-03-11T05:00:00Z That means the frequency of the carrier wave—the basic radio wave, which is then deliberately deformed in order to carry data—rises and falls in a sawtooth pattern. A clever way to transmit data on the cheap 2017-09-13T04:00:00Z A carrier wave having the basic frequency of the radio station, say 1530 kHz, is varied or modulated in amplitude by an audio signal. College Physics for AP Courses 2015-08-12T00:00:00Z The researchers modify their carrier wave by injecting a tiny warble at the frequency they hope to probe. To crack the mystery of dark matter, physicists turn to supersensitive quantum sensors 2022-04-27T04:00:00Z According to pbs.org, the difference between AM radio and FM radio is how the carrier wave is modulated, or altered. County’s rich radio history worth a listen 2016-10-05T04:00:00Z Ideology and theology are carrier waves, not the message. The Big Picture Take on Geopolitical Instability 2016-01-14T05:00:00Z Generating that carrier wave requires a lot of power. A clever way to transmit data on the cheap 2017-09-13T04:00:00Z So an AM receiver would interpret noise added onto the amplitude of its carrier wave as part of the information. College Physics for AP Courses 2015-08-12T00:00:00Z Other elements required to build the standard include the method of encoding data in the radio carrier wave and the frequencies to be used, Niri said. Samsung's 5G mobile claims played down by experts 2013-05-14T15:27:14Z This invention relates broadly to secret communications systems involving the use of carrier waves of different frequencies, and is especially useful in the remote control of dirigible craft such as torpedoes. Hedy Lamarr, The Most Glamorous Geek Of All Time 2011-11-28T04:07:14Z But to deal primarily with the carrier wave aspect is to be reactive and tactical; not strategic and in control of events. The Big Picture Take on Geopolitical Instability 2016-01-14T05:00:00Z When the aerial is earthed, part of the carrier wave will be absorbed. A clever way to transmit data on the cheap 2017-09-13T04:00:00Z An FM receiver can be made to reject amplitudes other than that of the basic carrier wave and only look for variations in frequency. College Physics for AP Courses 2015-08-12T00:00:00Z They use a specially tuned carrier wave of some sort, he said, that impinges on a thought wave pattern, but instead of registering the pattern's electronic impulse equivalents as does the electroencephalograph, it 'reflects' them. The Women-Stealers of Thrayx Carpenter replied that the rays of colored or visible light could only pass through the layer when superimposed upon a carrier wave of ultra-violet or invisible light. Astounding Stories of Super-Science September 1930 The EEG recording is simply fed into a gadget that modulates a carrier wave. The Electronic Mind Reader It is not involved as a necessity, for untuned currents may be broadcast at voice-controlled frequencies, directly and without any carrier wave. The Airlords of Han A radio receiver tuned to have the same resonant frequency as the carrier wave can pick up the signal, while rejecting the many other frequencies impinging on its antenna. College Physics for AP Courses 2015-08-12T00:00:00Z Orne heard the sudden hiss of the carrier wave in his neck transceiver, but there was no voice from the monitor. Operation Haystack Our projections are useless, as they can be driven only a very short distance upon our present carrier wave. Skylark Three We generate a blanket frequency, impressed upon the ultra carrier wave. Spacehounds of IPC I've found the electromagnetic frequencies that the various coral resonate on, and by using those as a carrier wave, I can stimulate them into tremendously accelerated growth. Home Again, Home Again The receiver’s circuitry is designed to respond to variations in amplitude of the carrier wave to replicate the original audio signal. College Physics for AP Courses 2015-08-12T00:00:00Z I learned later that it was the 'carrier wave' of a broadcasting station without modulation, but I didn't know what that meant. The Dawn of Amateur Radio in the U.K. and Greece: a personal view Walls, planets, even suns, do not bar our vision, because of the fifth-order carrier wave. Skylark Three Used as a pure carrier wave, with a sender and a receiver at each end, it isn't so bad—that's why our communicator and radio systems work as well as they do. Spacehounds of IPC We must see what we are doing, so the light-rays must be heterodyned upon our carrier wave. Skylark Three Therefore the carrier wave must have come through our whole system of screens without so much as giving an alarm. Skylark Three For he would of course grasp instantly the fact that you had used fifth-order rays as carrier waves, and would be able to deduce your ability to destroy. Skylark Three He imposed the audio system upon the inconceivably high frequency of their carrier wave and spoke in the Osnomian tongue. Skylark Three Well, anyway, by the use of suitable fields of force it can be used as a carrier wave. Spacehounds of IPC The carrier wave hissed into the receiver, forestalling Brandon's fiery reply, followed closely by the code signals they had been expecting. Spacehounds of IPC |
