例句 | With two modes, Traditional and Modern, it enables thereminists to switch between heterodyne analog and digital oscillators. Moog’s limited-edition theremin marks 100 years of weird sounds 2020-10-22T04:00:00Z This is done by heterodyning, a process which combines the light in the coupler with a minute laser beam, strengthening the signal at the desired wavelength. Cameras are about to get a lot smaller 2017-07-06T04:00:00Z Or how about how astronomers use heterodyne arrays with superconducting mixers to observe the birth of stars? 'Dance Your Ph.D.' finalists announced 2014-10-27T04:00:00Z When you have completed this experiment in heterodyne receiving, using a local oscillator, you are ready to try the regenerative circuit. Letters of a Radio-Engineer to His Son It is a heterodyning of one frequency upon another at a predetermined distance. Invasion They heterodyned it right back along my own beam. The Issahar Artifacts Our heterodyne or "radio-scrambling" broadcast had gone into operation, emitting impulses of constantly varying wave-length over the full broadcast range and heterodyning the Han communications into futility. The Airlords of Han "In this case, a heterodyne frequency of a lower, and harmless frequency." The Ultimate Weapon This method of receiving continuous wave signals is called the “heterodyne” method. Letters of a Radio-Engineer to His Son You folks can see just as well, even on the direct-vision wall plates, with light heterodyned on the fifth, so we'll close all ether bands, absolutely. Skylark Three Sending the heterodyned wave through steel is easy, but breaking it up, so as to view an object and return the impulses, was an awful job and one that isn't half done yet. Spacehounds of IPC But their valley forces were getting out of alignment a bit by now, owing to our heterodyne operations. The Airlords of Han If we try to heterodyne his radio—presto—it has twice the heat energy anyway, though we might reduce it to a frequency that penetrated the ship instead of all staying in it. The Ultimate Weapon The heterodyning of extremely saw-toothed waves produced peaks of energy until the saw-teeth began to smooth out. Operation Terror We must see what we are doing, so the light-rays must be heterodyned upon our carrier wave. Skylark Three One of the operators was E. Howard Armstrong inventor of the regenerative detector, super-regeneration and the supersonic heterodyne receiver, though the French claim that the superhet was first designed by Lucien Levy of Paris. The Dawn of Amateur Radio in the U.K. and Greece: a personal view If a heterodyne receiving set, see Chapter XV, is being used at the other end you can dispense with the chopper and the key circuit needed is very much simplified. The Radio Amateur's Hand Book There was a half-forgotten tingling as the weak field heterodyned his thought waves. The Lani People There it is heterodyned with another wave—this second frequency was found after thousands of trials and is, I believe, the exact frequency existing in the optic nerves themselves—and sent to the receiving headset. Skylark Three He can penetrate the impenetrable shield of force and can operate mechanisms of pure force behind it; he can heterodyne, transmit, and use the infra-rays, of whose very existence we were in doubt until recently! Skylark Three The heterodyne method will be described in this chapter. The Radio Amateur's Hand Book The waves radiated by this transmitter can be received by either a crystal detector or a plain vacuum-tube detector but the heterodyne receptor will give you better results than either of the foregoing types. The Radio Amateur's Hand Book The Separate Heterodyne Long Wave Receiving Set.—This is a better long wave receptor than the self heterodyne set described above for receiving wireless telegraph signals sent out by a continuous long wave transmitter. The Radio Amateur's Hand Book A graphic representation of the oscillating currents set up by the incoming waves, those produced by the heterodyne oscillator and the beats they form is shown in Fig. The Radio Amateur's Hand Book They must then be reflected from the object seen, must be gathered together, again heterodyned upon the fifth-order carrier, and retransmitted back to us. Skylark Three The Separate Heterodyne Receiving Set.—The better way, however, is to use a separate vacuum tube for setting up the heterodyne oscillations. The Radio Amateur's Hand Book In using either of these heterodyne receivers be sure to carefully adjust the B battery by means of the potentiometer. The Radio Amateur's Hand Book This, then, is the principle of the heterodyne, or beat, receptor. The Radio Amateur's Hand Book |
