ECG(Electrocardiography) amplifier and filter circuit design on MATLAB simulink-simscape
What is an ECG? ECG is an abbreviation for electrocardiography. A heart's electrical activity can be known by the ECG test. A set of electrodes are used to capture the biopotentials and convert them into electrical signals. The ECG is basically a 2D plot of time v/s voltage. The measured ECG signal that is the output voltage of the set of electrodes is in the range of 1mv to 5mv approx. This needs to be amplified using a high gain amplifier. The ECG signal also contains noises. There are mainly 3 types of noise. 1. 50Hz noise due to the powerline. 2. High-frequency noise (Electromyogram -EMG noise). 3. Additive white gaussian noise. 4. Low-frequency noise (Baseline wandering). Noisy ECG signal with baseline wandering 1. Amplifier circuit design: ...
