Amplitude Formula definition with Example
Amplitude Formula Definition – The amplitude of a variable is a measure of its change over a single period. The maximum height observed in the wave is called as Amplitude. It is denoted by A and is given in decibels (dB). The sine wave is represented as Where A is amplitude and ω is angular frequency. The Amplitude Formula is given by
Amplitude Formula Example
Question 1: Find the amplitude of the wave if the wave is represented by y = 3 sin
The equation is of the form y = A sin t. Hence the amplitude is A = 3.
The amplitude is given by A = A =
= 0.1 decibels.
