In the decades since the book was published, the â21 daysâ idea has been repeated so often that itâs become accepted as fact. But to make a new habit, you're really asking your brain to learn a new behavior, and it takes more time to learn some tasks than others.
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.

The audio waveform modifies the amplitude of the carrier wave and determines the envelope of the waveform. In the frequency domain, amplitude modulation produces a signal with power concentrated at the carrier frequency and two adjacent sidebands.he audio waveform modifies the amplitude of the carrier wave and determines the envelope of the waveform.
