Amplitude Amplitude

rdfs:comment

Amplitude is the distance from the centre line of a wave to the top of its crests. If a wave has a high amplitude, it carries more energy than one with low amplitude. In the case of sound, this is perceived as loudness. < [[w:|]][[Category: derivations|Amplitude]] amplitudo < amplus (“‘large’”); see ample and -tude. The extent to which a waveform (as displayed on an oscilloscope) rises above, or falls below, the X-axis. The difference between the highest point and the lowest point is referred to as the peak ampltude. Various mathematical schemes such as root-mean-square (RMS) exist which average the amount of time the signal is above or below the axis; these measure, for example, the amount of power required to amplify the signal to a given peak amplitude. The average amplitude is proportional to the volume of the signal. See also amplitude modulation, envelope. The amplitude is a measure of the value of a radio wave, measured in volts.
