Multiple Patients ECG Monitoring Using Daubechies Wavelet Filter

Vidhya.R, Felcy Jeba Malar.M

Abstract: A portable multi monitoring ECG system is proposed using conveyable Daubechies wavelets filter with memory based APC and OMS techniques which gives rise to the multiple patients ECG monitoring within single unit. This technique uses only odd multiples that are stored in LUT-s and even multiples that are achieved by shifting operation. It significantly reduces the equivalent data-rate of the ADC output without affecting the information content of the input signal, leading to a reduction of data memory access processing complexity. This happens because the Daubechies wavelets filter doesn-t use the feedback loop. Low power consumption around 69.08mW is achieved. By using this technique, best results for multiple patient ECG samples is obtained.
