If we tried to calculate the average amplitude of a sine wave, it would unfortunately equal zero, since it rises and falls symmetrically above and below the zero reference. This would not tell us very much about its amplitude, since low-amplitude and high-amplitude sine waves would appear equivalent.

calculate an amplitude value based on aprobability density and a noise variance based on the amplitude value; calculate a second SNR based on the amplitude value and the noise ... This is achieved by calculating amplitude estimates A'.sub.0, A'.sub.1 and A'.sub.m using Equation 30 instead of Equation 24 in step 204.

We could first use the following equation to calculate amplitude values for one waveform. ... We can calculate the amplitude, Ax, using the guitar string’s wave equation by plugging in various values that represent the position “x” along the string. We say that the amplitude of a guitar string is a function of...
