The amplitude of the food at the buffet delighted the hungry guests.
An amplitude is also a measurement that indicates the movement or vibration of something; such as, a sound wave or a radio wave.2. Etymology: from Latin amplitudo, from amplus, "ample, large quantity" + -tude, "quality, condition of".
Variation of the amplitude modulation of a carrier wave, commonly a radio wave, presents fluctuations in the audio or video signals that are being transmitted.
A higher amplitude modulation wave is interpreted as a "1" and a normal wave is interpreted as a zero.
The method of changing an amplitude modulation is known as "amplitude shift keying", or ASK.
