一种新型沃尔什函数发生器

A NEW TYPE OF WALSH FUNCTION GENERATOR

采用Ｔ触发器建立了一个新型沃尔什函数发生器的软硬件统一模型，并对设计时所需要的多路激励信号作了较深入的分析，归纳并证明了它们的两个重要特性──反对称特性和递推特性．实验证明，按照统一模型设计沃尔什函数发生器，可以使设计过程大为简化，而且输出的沃尔什函数具有最小正交误差．

A new type of unified model of software and hardware of Walsh function generator were designed with T trigger. The multiplex driving signals needed in design are deeply analysed,then two important properties─antisymmetry and recursion property are induced and proved. The experiments illustrate that the Walsh function generator based on the unified model can simplify the design and the Walsh wave has the minimum orthogonality error.
