应用微机产生多频信号的技术

TECHNIQUE OF PRODUCING MULTIFREQUENCY SINGAL ON PC COMPUTER

本文介绍了一种新型实验信号的产生方法。这种信号具有现有信号的主要优点。信号用优化技术进行合成后,在微机上进行数模转换,经过放大和滤波后即可作为实验的信号源,使激振器产生预期的激振力。

The method to produce a new kind of test signal is discussed in this paper. The signal has the main advantages of existing ones. The signal is obtained from IBM computer after optimizing. It can be used in an electric-magnic exciter after amplifying and filtering.
