Abstract

The electrocardiogram (ECG) signal plays a crucial role in biological signal processing, particularly in the field of medical diagnostics. This study is dedicated to exploring the utilization of passive components in ECG signal processing to devise an economical device aimed at amplifying physiological signals. In the hardware setup, we employed both pre- and post-amplifiers, bandpass filters, and notch filters to achieve specific objectives, including signal amplification, white noise reduction, and removal of power frequency interference. Complementing the hardware components, our software approach involves the implementation of an R peak extraction method to accurately determine heart rate following rigorous denoising preprocessing procedures. The primary objective of this research endeavor is to offer a practical and cost-effective solution for ECG acquisition, particularly beneficial for regions characterized by limited access to electricity and constrained economic resources. Through this study, we anticipate contributing to the advancement of biomedical engineering by facilitating enhanced ECG signal acquisition methodologies in resource-limited settings.
