VCO之时域频稳度与频域频稳度之间的联系及测量

THE RELATION AND MEASUREMENT OF STABILITY BETWEEN FREQUENCY REGION AND TIME REGION OF VCO

扼要说明ＶＣＯ之短期稳定度的两种表征量，并给出国际上推荐的ＳＹ（ｆ）和σ２Ｙ（τ）的定义，推算出二者的联系与一种同时测量ＳＹ（ｆ）和σ２Ｙ（τ）的方法。

Two expressions of VCO short time stability are stated briefly with a definition to S Y(f) and σ 2 Y(τ) recommended by international organizations.Then the relation between the two and a way of measuring S Y(f) and σ 2 Y(τ) at the same time are also given.
