Question

Given the ECG signals, ecgdemodatal.mat, Calculate the Spectrum of the ECG signal. Use a sampling frequency of 1000 Hz or more Use FFT to computer the Spectrum Tasks

01. Read the ecgdemodata1.mat

Answer 1

To calculate the spectrum of the ECG signal, you can use the Fast Fourier Transform (FFT) algorithm. Here are the steps: 1. Read the ECG data from the file ecgdemodata1.mat. 2. Set the sampling frequency to 1000 Hz or more. 3. Apply the FFT algorithm to the ECG signal. 4. Plot the spectrum of the ECG signal.

Step-by-step explanation:

An electrocardiogram (ECG) is a recording of the voltages created by the wave of depolarization and subsequent repolarization in the heart. To calculate the spectrum of the ECG signal, we can use the Fast Fourier Transform (FFT) algorithm. Here are the steps:

1. Read the ECG data from the file ecgdemodata1.mat
2. Set the sampling frequency to 1000 Hz or more
3. Apply the FFT algorithm to the ECG signal
4. Plot the spectrum of the ECG signal
