摘要
随机信号是宽频带随机激振方式的基础。在缺少宽频带随机信号发生器的情况下,本文将论述如何用软件方法实现随机信号发生器在Windows环境下,根据MicrosoftMultimediaKit提供的接口,用BorlandC++ObjectWindowsLibrary[1]设计声音WAVE文件,并由EM88美王声卡输出随机信号。
The random signal is the base of the wide freguency exciting method. This article hasdiscussed the principle which applies the multiple technology to realizing the random signal, underthe window platform, according to Microsoft Multiple Kit Interface, using the Borland C+ + object Window Library to design the WAVE File, and playing the signal throUgh ES 688 aboundCommander.
