Abstract
Heart data acquisition is actually common these days to prevent its atypical functioning. However, it presents some issues like noise or the overlapping of spectra of the rest of the human body signals. Consequently, the electrocardiogram (ECG) is the most common way of heart monitoring. However, ECG electronic systems have not a portability criterion. To do so, the present system shows filter hardware and software design to improve ECG data acquisition through signal processing. For the one hand, it presents the sensor design, signal coupling, and band-pass filter Sallen-key structure. For another hand, the system implements a function transfer with Triangular and Gaussian filter stages. As a remarkable result, the output signal is a significant noise reduction.
