| 摘 要： | 给出了一种异步时钟恢复的最佳平方逼近插值滤波器设计，该滤波器基于最小平方逼近理论，采用易于硬件实现的Farrow结构；克服了拉格朗日插值滤波器参数固定而窗函数截短插值滤波器结构复杂的问题。对我国航天测控设备的数字化和小型化具有较好的应用价值。

| Abstract: | A loop filter based on the theory of least square approximation is designed.The filter is realized in Farrow structure.It overcomes the shortcomings of unchangeable parameters in Lagrange filter and the complexity of filters based on window's functions.The loop filter introduced in the paper is practical and valuable in timing recovery for digital receivers. |
