A digital signal processing system for time series analysis with two modes of usage--the first a rapid, hands-on exploratory method, and the second an automatic, printed, labeled graphic output method--is described. The system utilizes a Time Data 1923C system with integral PDP-11 minicomputer, and a console. Major error problems have been contained and a large-volume graphic analysis capability has been developed. Applications include (a) transpulmonary pressure-pulse relationships, (b) elucidation of the multiphasic nature of pulmonary-vein/left-atrial-pressure pulse phenomena, (c) suggestive value of transfer function phenomena as a tool to demonstrate the effect of various loading and ischemic phenomena on the left ventricle, and (d) teaching-demonstration of the techniques of digital signal processing.
描述了一种用于时间序列分析的数字信号处理系统，该系统有两种使用模式——第一种是快速的、亲身实践的探索方法，第二种是自动的、打印的、带标签的图形输出方法。该系统利用带有集成PDP - 11小型计算机的Time Data 1923C系统和一个控制台。主要的误差问题已得到控制，并且已开发出大容量图形分析能力。其应用包括：(a) 跨肺压力-脉搏关系；(b) 阐明肺静脉/左心房压力脉搏现象的多相性质；(c) 传递函数现象作为一种工具来证明各种负荷和缺血现象对左心室影响的提示价值；以及(d) 数字信号处理技术的教学演示。
