A Preferable Method on Digital Filter in ECG Signal's Processing Based on FPGA
Nianqiang Li, Yongbing Wang, Guoyi Zhao · 2010
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.
