FPGA-based implementation of an adaptive canceller for 50/60-Hz interference in electrocardiography

The implementation of an adaptive canceller of interference using a field-programmable gate array (Xilinx) programmable logic device/mechanism is shown in this paper. The adaptive canceller automatically adjusts its parameters to eliminate noise. This ability allows the canceller to adapt to changes in the characteristics of the signal. The use of this adaptive canceller to filter the interference noise that is caused by the power line is shown.
