振蕩器中存在着由內部元件所产生的噪声成分。这就是振蕩器的輸出頻譜变寬的原因。作为減輕这种影响的措施,是把两个振蕩器耦合起来,使之相互同步,这样便可获得与“插入同步”同样的減輕噪声的效果。本文是分析包含噪声的雷利型相互同步振蕩器,并說明用电容和电阻的耦合来減輕噪声的效能。另外,本着更詳細地討論这一結果的想法,还进行了数值計算,以及定量地表示出輸出頻譜的加寬程度。最后,为了更进一步証实这些結果而进行了实驗。現已认定:电容、电阻耦合,都有減輕噪声的效果。特別是在电容耦合时,加强耦合度的效果就更为显著。
There are noise components generated by the internal components in the oscillator. This is why the oscillator output spectrum broadens. As a measure to mitigate this effect, the two oscillators are coupled and synchronized with each other so that the same noise-reducing effect as “Insert Sync ” is achieved. This article analyzes Rayleigh-type mutual synchronous oscillators that contain noise and illustrates the effectiveness of noise reduction by coupling capacitors and resistors. In addition, based on the idea of discussing this result in more detail, numerical calculations were carried out and the extent of broadening of the output spectrum was quantitatively demonstrated. Finally, experiments were conducted to further confirm these results. Has now been identified: capacitance, resistance coupling, all to reduce the noise effect. Especially in the capacitive coupling, the effect of strengthening the coupling is even more significant.
