Signal Maximum Relative Error

MaximumRelativeError

Primitives for computing the MaximumRelative error between two signals. Given two signals \(pSrc1\) and \(pSrc2\) both with length \(N\), the maximum relative error is defined as

\[MaximumRelativeError = max{\frac{\left|pSrc1(n) - pSrc2(n)\right|}{max(\left|pSrc1(n)\right|, \left|pSrc2(n)\right|)}}\]

If the signal is in complex format, the absolute value of the complex number is used.

Signal Average Relative Error

AverageRelativeError

Primitives for computing the AverageRelative error between two signals. Given two signals \(pSrc1\) and \(pSrc2\) both with length \(N\), the average relative error is defined as

\[AverageRelativeError = \frac{1}{N}\sum_{n=0}^{N-1}\frac{\left|pSrc1(n) - pSrc2(n)\right|}{max(\left|pSrc1(n)\right|, \left|pSrc2(n)\right|)}\]

If the signal is in complex format, the absolute value of the complex number is used.
