耦合回路相位鉴频器鉴频曲线的推导

Deduction of the frequency discrimination curve of coupling loop phase discriminator

目前国内对相位鉴频器鉴频曲线的推导,均采用矢量合成法,这是一种在粗略意义上的描述。本文通过其数学模型,演算推导出鉴频曲线的数学表达式,从中可以清晰地看出电路中各元件参数对曲线的影响。

The vector synthesis phase is adopted to deduce the frequency discrimination curve of discriminator, which is the sketchy description. The article deduces the mathematical way of expression of the frequency discrimination through the mathematical model. We can find clearly the influence of component parameter on curve from it.
