A Preferable Method on Digital Filter in ECG Signal's Processing Based on FPGA

Digital filter is one of the most important components in electrocardiogram (ECG) signal's processing. This research method combined Fast Fourier Transform (FFT) & Wavelet Threshold De-noising (WTD) to meet the demand that the ECG signal's sampling and processing must be exact, real-time and steady. Meanwhile, the high performance of Field Programmable Gate Array (FPGA) also satisfied the demand for a high speed when it samples and processes the data from ECG device.
