| 摘要: |
| 本文讨论了数字横向滤波器实现频率鉴别的原理。具体分析了利用自相关及自复卷积方法实现频率鉴别的方法，得出了鉴频特性斜率值及鉴频带宽的关系式，计算并给出了鉴频特性∑I～ω、⊿Q～ω 的关系曲线。这种频率鉴别方法可以用在接收相参系统中的自动频率微调。 |

| Frequency Discrimination by Digital Transversal Filter |
| Sun Zhongkang |
| Abstract: |
| The principle of frequency discrimination(FD) by digital transversal filter is discussed. A detailed analysis of the FD method by autocorrelation and auto-convolution is given and the slope and bandwidth of the characteristics of FD is obtained. In addition，the curves ∑I～ωand⊿Q～ω are computed and given in this article.
This FD method can be used for AFC of the coherent-on-receive system. |
