本文对一套纠错电路的有关理论问题和具体实现过程进行讨论。一方面,就RS纠错理论的关键,拟循环与逆向拟循环之问的关系问题,向读者介绍在实际工程中非常有价值的所谓“原地设计”思想。另一方面,就其理论的具体实现,向读者介绍根据实际工程的需要应考虑优化问题,使其尽可能做到规范化和减少基本元部件以降低成本的思想。 This article discusses a set of error correction circuit theory and the specific implementation process. On the one hand, we will introduce to readers the so-called “in-situ design” thought that is very valuable in practical engineering on the key of RS error correction theory and the relationship between quasi-loop and reverse quasi-loop. On the other hand, on the concrete realization of its theory, it introduces readers to the idea of ​​optimizing the problem according to the actual project needs, making it as standard as possible and reducing the basic components so as to reduce the cost.
