摘要: In this paper, an analysis of capnogram to differentiate asthmatic and non-asthmatic patients is presented by using linear predictive coding (LPC) technique. the previous studies, manual study on signal has been conducted several researchers. All researches show significant correlation between patient. However all them are just through conventional time domain method. preliminary, a number 8 LPC coefficients (α1- α8) for both (CAP) patients’ (CNP) extracted. Usefulness performance these conditions means receiver operating characteristic (ROC) curve shown. Our preliminary results that α3, α4, α5, α6 can be used distinguish conditions.
