摘要
在现代遥测系统和其它相关的数字通信系统的码同步器中广泛采用了随机徘徊滤波器技术以提高电路的抗干扰能力和系统工作的可靠性.在本科生专业课的实验教学中,能够利用先进的实验装置和手段深入地学习和掌握系统的基本原理,形象具体地了解随机徘徊滤波器的工作过程是我们所期望的.介绍一种自行研制的在实验教学中取得良好效果的随机徘徊滤波器原理实验电路板,并对其设计思想、硬件组成及工作原理作了较为详细的介绍.
Random- walk filter is widely used in Bit Synchronizer of modern telemetry system and other digital communication systems in order to enhance anti-jamming ability and reliability of a system. In the specialty experiment teaching of undergraduates, that they are not only able to make use of advanced experiment equipment and instruments for better understanding and good command of fundamentals of a system, but also can visually and concretely comprehend working process of random- walk filter is what we expect. In this article, we introduce a circuit plate of Random- walk filter designed by ourselves which functions efficiently. The design, hardware composition, and function principles are also mentioned in detail.
