某型电台音频电路板测试系统DSP设计与开发

摘要

文章研制的基于DSP的某型音频电路板测试系统用以实现对音频信号的参数自动采集和测试，并利用触摸屏进行人机交互，实时显示测试结果，检测过程准确、准确，可广泛应用于音频电路板的测试、检验、维护和故障定位。%In this paper,the developed audio circuit board testing system of some station based on DSP is used to realizing the auto acquisition and testing of the parameters of audio signal, and we use touching screen to realize man-machine interactive and real-time display testing results. The detecting process accurate and quick,so it can be widely used in the testing , checking, maintenance, fault location and so on of the station’s audio circuit board.
