A features enhancement adaptive structure for removing residual power-line interference

Summary form only given. Power-line interference is a common problem in biopotential measurement. For fixing drawbacks of traditional methods in interference cancellation, we propose all adaptive filtering structure to minimize the residual power-line interference in practical corrupted biosignals. Although the collected data is contaminated with power-line interference, with this structure, an experiment need not be redone nor are other measures needed to protect from EMI/EMC interference. One does not have to modify the circuit allocation of present instruments to make room for an extra reference channel. After several tests, the result of this structure is satisfactory and acceptable for clinical measurements.
