For clinical purpose, poligraphyc signals are analyzed: systolic time intervals (STI) and all other significative magnitudes are measured. A system of modular programs (ATS), in Assembler and Fortran IV languages, digitalizes, filters and analyzes three simultaneous analogical signals: ECG, PCK and CP. ATS, adapted polynomial and gonyometrics leats-squares smoothings to the signals for leaving-out spikes and drifts, employs algorhythms that, by a statistic knowledge of the thresholds of the fist derivative of each signal and of the globality of smoothed signals, converge to the measures of the required significative magnitudes. A statistic investigation (on 100 samples) showed that ATS is better than every manual analysis in terms of efficiency, speed and amount of information. In conclusion ATS program is suitable for clinical purposes.
出于临床目的，对多导睡眠图信号进行分析：测量收缩期时间间隔（STI）及所有其他有意义的量值。一个用汇编语言和Fortran IV语言编写的模块化程序系统（ATS），对三个同步模拟信号（心电图、脉搏图和呼吸图）进行数字化、滤波和分析。ATS对信号采用自适应多项式和测角法最小二乘平滑处理以去除尖峰和漂移，运用算法，通过对每个信号一阶导数阈值及平滑信号全局情况的统计知识，得出所需有意义量值的测量结果。一项（对100个样本的）统计研究表明，在效率、速度和信息量方面，ATS优于任何人工分析。总之，ATS程序适用于临床目的。
