1.	Which techniques are used in a new algorithm proposed by Jen and Hwang to obtain the long term ECG signal feature and extract the meaningful information hiding in the QRS complex?(a) Cepstrum time warping and Dynamic coefficient(b) Cepstrum coefficient and Dynamic time warping(c) QRS detection and Dynamic coefficient(d) QRS detection and Cepstrum time warpingI got this question in a national level competition.This interesting question is from Phonocardiography (PCG) in division Biomedical Recorders of Biomedical Instrumentation
Answer» Correct OPTION is (b) Cepstrum coefficient and Dynamic time warping Easy explanation: Jen and Hwang proposed a new algorithm using cepstrum coefficient and the dynamic time warping techniques to obtain the long term ECG signal feature and EXTRACT the meaningful information hiding in the QRS complex. This algorithm may ALSO be used for arrhythmia detection by simply checking the difference of R-R wave INTERVALS through signal feature extraction comparison for a certain period of time.
