Amplitude Definition Math

For the sine function the amplitude is given by and the period is defined as.

Amplitude definition math. In other words for functions of the form y a sin bθ or y a cos bθ the amplitude is a. The amplitude of a periodic variable is a measure of its change in a single period such as time or spatial period there are various definitions of amplitude see below which are all functions of the magnitude of the differences between the variable s extreme values in older texts the phase of a period function is sometimes called the amplitude. See also sine wave. The starting point of the measurement is the flat calm surface of the water.

The same is true for a cosine function. Or we can measure the height from highest to lowest points and divide that by 2. Another way to find the amplitude of a periodic graph is to find the difference in height between its highest and lowest points and divide it by 2. The height from the center line to the peak or trough of a periodic function.

Amplitude is the height from the mean or rest value of the function to its maximum or minimum. Amplitude is half the distance between the minimum and maximum values of the range of a periodic function with a bounded range. Definition of amplitude the amplitude is the distance from the centre line to the peak or trough of a periodic function. In an electrical circuit operating on alternating current ac amplitude is measured as the voltage v level and is expressed as v and v depending on the direction of the current.

Amplitude is a measure of the intensity loudness power strength or volume level of a signal. Try adjusting the amplitude below.
