Wearable biomedical devices for recording electrocardiograms (ECG) are becoming more and popular as they provide clinicians with a comprehensive view of patient's diagnosis. ECG signals characterized by low amplitude susceptible to many kinds noise, so high gain common mode rejection ratio (CMRR) essential suppress them, while ultra-low power noise (AFE) is used Analog front-end signal acquisition, based on Drive Right Leg (DRL) circuit that combines common-mode feedback CMRR notch filter...

Abstract Direction repulsion is a perceptual illusion in which the directions of two superimposed surfaces are repulsed away from real motion. The reduced when differ dorsal stream features such as speed. We have previously shown that segmenting by color, ventral feature, did not affect but instead time needed to process both surfaces. current study investigated whether feature coprocessed with direction (i.e., speed) would also reduce processing time. found increasing speed one or...
