______________ 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 warpingThe question was asked in an online quiz.My question is from Clinical Data Interchange/Exchange Standards topic in portion Telemedicine Technology of Biomedical Instrumentation

Answer»

The correct OPTION is (b) CEPSTRUM coefficient and Dynamic time warping

To explain I would say: 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. 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.
