目前的工作是我们开发多相振荡器工作的一部分。这里处理的特定系统是强非线性耦合的四个振荡器，形成一个多相源。这种源在电力电子、相控阵天线和现代调制方法中具有潜在的应用，特别是在解调多相调制信号中。本系统可以被解释为包含四个两相振荡器。然而，作为强耦合的结果，每个振荡器的第二状态方程与下一个振荡器的第一方程合并。因此，所得到的四相源仅由四个状态方程表示。与通信相关的应用（特别是与接收机相关的应用）可能会受到源的噪声性能的影响。我们相信，目前建议的系统，它依赖于强耦合的振荡器，是有利的，在其噪声性能相比，最近描述的更简单的多相源，其中包括松散耦合的振荡器。版权所有© 2007约翰威利父子有限公司
The present work is a part of our effort of developing multiphase oscillators. The particular system dealt with here is that of strongly nonlinearly coupled four oscillators that form a multiphase source. Such sources possess potential applications in power electronics, in phased‐array antennas, and in modern methods of modulation and especially in demodulating multi‐phased modulated signals. The present system can be interpreted as embracing four two‐phase oscillators. Nevertheless, as a result of the strong coupling, the second state equation of each oscillator merges with the first equation of the following oscillator. The resulted four‐phase source is, therefore, represented by merely four state equations. The applications related to communications (especially those related to receivers) may be susceptible to the noise performance of the source. We believe that the presently suggested system, which relies on strong coupling of oscillators, is advantageous in its noise performance in comparison to more straightforward recently described multiphase sources, which incorporate loosely coupled oscillators.
