释义	oscillatoros‧cil‧la‧tor /ˈɒsəleɪtə $ ˈɑːsəleɪtər/ noun [countable] Examples EXAMPLES FROM THE CORPUS A neat example of a sinusoidal oscillator is the Wien bridge oscillator shown in figure 10.13. Band filters that can be tuned down to low frequencies are useful in a host of applications including electronic oscillators. Fig. 3 shows the basic circuit of such an oscillator. In practice the rate at which samples are passed along the device is controlled by a clock oscillator. The analysis reported here has been motivated by investigations of high-frequency cellular oscillators with periods of the order of minutes or less. The arrangement of counters allows a range of oscillator frequencies to be adopted. The final technique for producing a velocity profile involves a voltage.controlled oscillator with the controlling voltage generated by an analogue circuit. word sets WORD SETS► Electrical alternator, nounarc, nounblow, verbcapacitor, nouncathode, nouncell, nouncharge, nouncharge, verbcharger, nouncircuit, nouncircuit board, nouncircuit breaker, nouncircuitry, nouncoil, nouncondenser, nounconnection, nouncontact, nouncord, nouncordless, adjectivecurrent, nounDC, dimmer, noundirect current, noundischarge, verbdischarge, nounE, earth, nounearth, verbelectric, adjectiveelectrician, nounelectricity, nounelectrics, nounelectrode, nounelectronic, adjectiveelectronics, nounfuel cell, nounfuse, verbfuse box, nounfused, adjectivegrid, nounlive, adjectivelive wire, nounmagic eye, nounmagneto, nounnegative, adjectiveneutral, adjectivenoise, nounoscillate, verboscillator, nounoutlet, nounphotoelectric, adjectivephotoelectric cell, nounpin, nounplug, nounpoint, nounpre-set, adjectiveprinted circuit, nounprogramme, nounprogramme, verbpulse, nounremote control, nounresistance, nounresistor, nounscan, verbscanner, nounshort, nounshort, verbshort circuit, nounshort-circuit, verbsocket, nounsolid-state, adjectivesonar, nounsuperconductivity, nounsuperconductor, nounterminal, nountime switch, nountoggle switch, nountorch, nountransformer, nountransistor, nounvacuum tube, nounvalve, nounW, wire, nounwiring, nounzapper, noun technical a machine that produces electrical oscillations
