【摘要】 | 为了从分相码流中提取时钟信号,本文介绍了三类非线性同步器,它们都能产生时钟频率分量及其谐波。本文推导出估算时钟频率分量的功率和由限带白噪造成的定时误差公式,并且指出有几种同步器的性能与信号统计特性无关。分相码的这一重要优点是以加宽频带换取的。 |
【英文摘要】 | For extraction of clock signal from a noisy split phase coded data stream, three different types of nonlinear-filter synchronizer are described in this paper. All three types can produce spectral line component at clock frequency and its harmonics. Formulas for evaluation of the power of the clock frequency component and of the timing error due to bandlimited white noise are derived. Moreover, it is pointed out that the performance of some types of synchronizer is relatively independent of the signal statis… |
