Electrocardiogram (ECG) Sample Data
Resting ECG - Lead I (500Hz)
A clean, 60-second recording of a resting adult at 72 bpm. Clear P, QRS, and T waves. Contains 0.2 Hz respiratory baseline wander and Gaussian electrode noise.
Electroencephalogram (EEG) Sample Data
Eyes Open / Eyes Closed Alpha Block (250Hz)
Multi-channel 8-node recording (Fp1, Fp2, C3, C4, P3, P4, O1, O2). The subject closes their eyes at t=30s, generating a massive surge in occipital alpha (8-13Hz) waves.
Electromyogram (EMG) Sample Data
Bicep Flexion - Max Voluntary Contraction (1000Hz)
Surface EMG recorded over the biceps brachii during 3 distinct contraction bursts. Contains typical low-frequency movement artifacts (~3 Hz) at each burst onset.
