ECG Signal Generation with Noise Addition and Filtering
This experiment involves generating an ECG signal, adding noise, and then applying filtering techniques. Starting from an ECG signal data table, we first process the original signal containing known noise through filtering to obtain a clean ECG waveform. We then intentionally add high-frequency and mid-frequency noise to simulate real-world conditions. The noisy signal is displayed and filtered again to demonstrate noise removal. Each time-domain signal is visualized alongside its corresponding frequency spectrum for analysis. Different filter types are implemented and compared throughout the process to evaluate their performance characteristics.
