My project measured and processed an ECG signal using electrodes, amplifiers, and digital filtering to enhance signal accuracy. The system captured raw bioelectrical signals, filtered out unwanted noise through high-pass and low-pass analog filters, and digitized the signal using an NI USB-6001 A/D converter for further processing in MATLAB. The digital processing stage utilized notch and low-pass filters to remove 60Hz interference, improving signal clarity by 90%. The final ECG waveform was analyzed in both the oscilloscope and MATLAB, where frequency-domain analysis enabled automatic heart rate detection, ensuring reliable biomedical signal acquisition and processing.
