Question:medium

EMG signals have the highest frequency among EEG, ECG, and EMG because

Show Hint

Frequency comparison: \[ \boxed{ \text{EMG}>\text{ECG}>\text{EEG} } \] EMG contains the highest-frequency components because of rapid muscle activation.

Updated On: Jul 14, 2026

Muscle fibers contract rapidly
Electrodes are invasive
Muscles generate large voltages
EMG uses DC amplification
