what is the principal difference between amplitude and frequency
Best Answer: Amplitude: measures how high and how low the waves travel compared to a straight line. Frequency: measures how many times per second the wave peaks. Four basic EEG brain waves: Delta waves, Theta waves, Alpha waves, and Beta waves constitute the standard lineup of EEG brainwave activity.requency: measures how many times per second the wave peaks.
