研究了频率相近的两个相互耦合的锁相或自激振荡器的行为。在两个自由运行的相互耦合振荡器的情况下，这两个振荡器要么被锁定到一个共同的频率，要么通过相互拉动相互作用。结果表明，受拉振子的中心频率较近，但它们并不一定从相反的方向靠近对方。结果还表明，相互注入的强度以及相互注入信号所经历的相移会影响两个中心频率的位置。文中还研究了当两个相互耦合的振荡器被锁相时，锁相环对边带位置和幅度的影响。还讨论了互注入信号所承受的相移对边带的影响。
Behavior of two mutually coupled phase-locked or free-running oscillators with nearby frequencies is studied. In the case of two free-running mutually coupled oscillators, the two oscillators are either locked to a common frequency, or they undergo through a mutual pulling interaction. It is shown that center frequencies of the pulled oscillators come closer, however, they do not necessarily approach toward each other from opposite directions. It is also demonstrated that the strengths of mutual injections as well as the phase-shifts experienced by the mutually injected signals, affect locations of the two center frequencies. The paper also studies impacts of phase-locked loops on the location and magnitude of the sidebands, when the two mutually coupled oscillators are phase-locked. Effects of the phase-shifts endured by the mutually injected signals on the sidebands are also discussed.
