杭州大学电子仪器厂和同济大学电气工程系合作开发和生产的“西湖牌LZ1型离线信号采集机”,最近通过了鉴定。西湖牌LZ1型离线信号采集机是一种新型图线信号采集机。该机与微型计算机相连能快速、准确地将以往病史、历史图线资料等采集进计算机内,配置上相应的数据处理软件包,便能进行幅值域、时差域、频率域以及ARIMA模型分析。西湖牌LZ1型离线信号采集机与实时信号采集仪相比,能解决以前存档的和长途邮寄的图线、病例分析,并能从自相关函数和互频谱来分析病变的可能
Hangzhou University Electronic Instrument Factory and Tongji University Department of Electrical Engineering to develop and produce “West Lake license LZ1 offline signal acquisition machine,” recently passed the appraisal. West Lake brand LZ1 offline signal acquisition machine is a new type of line signal acquisition machine. The aircraft connected to the microcomputer can quickly and accurately collect the past medical history and historical graph data into the computer and configure the corresponding data processing software package to analyze the amplitude domain, the time difference domain, the frequency domain and the ARIMA model . Compared with the real-time signal acquisition instrument, the LZ1 offline signal acquisition machine of Xihu brand can solve the previously reported and long-distance mailed maps and case analysis and analyze the possibility of the lesion from the autocorrelation function and the cross-spectrum
