The ecg_data.dat file contains an actual ECG data representing a real ECG signal

It was requested to add three different noise to the orijinal ECG signal
- Random noise at 50 Hz (simulating power line interference)
 - Random low-frequency noise below 0.05 Hz (simulating baseline wander)
 - Random high-frequency noise above 150 Hz (simulating muscle artifacts and other high-frequency disturbances)
 
The ecg_data_noisy.txt file is a data file that stores the noisy ECG signal

A filter circuit was designed and simulated in LTSpice to remove the introduced noise components. The filter.asc file is simulation file that contains a filter circuit

The filter.txt file is a data file that stores the filtered ECG signal
