VTUNEis the source voltage used to correct for offset voltages and could be provided by a filtered PWM signal from a microcontroller or driven directly from a low power DAC. The HPA remains configured as an inverting amplifier with gain of –R2/R1 and can be used to further...
David PlourdeDownload PDF As system designers search for power efficient, signal conditioning components, they may find that there are very few ICs available under 100 μA supply current and even fewer that include a small package variant. With battery life and board space b...

(ECG) is a low-cost non-invasive sensor that measures conduction through the heart. By interpreting the morphology of a person’s ECG, clinical domain experts are able to infer the functionality of the underlying heartbeat, and diagnose irregularities. Moreover, a variety of signal processing ...
The paper analyses challenges for digital signal processing that arise from data acquisition from the mobile user are presented with focus on the electrocardiogram (ECG). Influence of the analysed challenges is demonstrated on a selected QRS detection algorithm by using signals from the MIT-BIH Noise...
. For correct evaluation of measured signal there is a need to processing the measured signal to suitable form. At present, the use of electrocardiograms with sensors with contact scanning are difficult to set a time so we decided to use the principle of non-contact sensing. Such a device ...

The Savitzky-Golay(SG) filters are widely used for smoothing and differentiation in many fields namely in elastography, EEG and magnetocardiogram signal processing and mainly in absorption spectroscopy. Despite their exceptional features they were rarely used so far in the ECG signal processing. The ...
