(在多数运用中,只有四种主要的关系。此处是初步的讨论,帮助消除混淆。)频率合成器已为许多工程师所喜爱,但该仪器对他们来说还是比较新的。某些指标——如相位噪声和转换速度——不适用于其它仪器。在多数频率合成器运用中,可能容易混淆的只有四个最重要的指标,即:稳定度、寄生 (In most applications, there are only four major relationships.) Here is a preliminary discussion that helps to eliminate confusion.) Frequency synthesizers have become popular with many engineers, but the instrument is still new to them. Some metrics - such as phase noise and slew rate - do not apply to other instruments. In most frequency synthesizers, there are only four of the most important indicators that can be easily confused: stability, parasitics
