Proposed Title :

• FPGA Implementation of Electrocardiogram Noise Removal using Sparse FIR Filter Design via Partial 1-Norm Optimization

Improvement of this Project:

• Design this sparse FIR filter on noise removal in electrocardiogram signal with support of Band pass FIR filter.

• This Proposed Band pass FIR filter will construct using High Pass FIR filter at 5 Hz frequency range, and Low Pass FIR filter at 15 Hz frequency rages, the cut off frequency of band pass filter is 5 to 15 Hz.

Software implementation:

• Modelsim
• Xilinx

Proposed System:

Electrocardiogram (ECG) is a form of cardiovascular measurement, for the diagnosis of different heart rate conditions. However, numerous noises usually harm the amplitude and time period of the signal from the ECG signal, at following a transition of the analog ECG signal from the sensor module into a digital format. The appropriate digital filter may be used to remove different forms of noise such as Baseline Wander, Power line interference, High frequency noise and Physiological Artifacts. The Digital FIR filter will have prospected to reduced the artifacts in the ECG signals. The signals taken from the MIT-BIH data base which contains the normal and abnormal waveforms. This Digital FIR filter can have more performance by using more TAP numbers such as multiplying, delaying and getting more effectiveness. This proposed work would implement a 1 norm minimization in the FIR filter with liner step method to minimize sparse complexity and reduce the mini-max approximation error for sparse maximization. Given these facts, several rules for selecting indicators of potential zero coefficients to be used in 1 standard optimization are adopted in the proposed algorithm. The efficacy of the proposed design algorithm was developed in Verilog HDL, simulated in Modelsim software and synthesized in Xilinx vertex 5 FPGA, and finally prove all the parameters in terms of area, delay and power.
