摘要
本文介绍了由PC/XT微机构成的吞水音信号数字分析系统。系统实现了在高噪声中提取吞水音信号并对信号进行时域和频域分析,用正负峰值采集法实现了小内存完成大批数据采集,能在无汉字系统支持下实现汉字输入和显示,并可在打印机上获得高质量的吞水音图。
The phagaquosonogram digital analysis system based on IBM PC/XT microcomputer is described in this paper. The method of collecting positive peak value and negative peak walue is applied in the system. The system realize to get signal's paramaters from high noise, and analyse signal in time-domain and frequency-domain. The chinese character can be inputed and displayed without chinese charaeter system, and the high quality duplicating phagaquosonogram can be given directly by applying the printer's commands.
