摘要
叙述了从研究沃尔什函数的复制理论和方块脉冲函数移位方法出发，推出桥函数的构造过程．桥函数把工程中常用的沃尔什函数和方块脉冲函数这两种似乎不相关的函数联系了起来．本文详细地给出了四种桥函数的构造过程和它们的波形．
The construction process of the Bridge functions is described in this paper after studying the copy theory of Walsh functions and the shift method of block functions. Bridge functions link Walsh functions with block functions which are usually used in engineering and considered to be indepedent each other. The paper also gives the construction process of four kinds of Bridge functions and their waveforms in detail.
