Abstract
In a chain of linear time-invariant operations ( ), all bias introduced between operations collectively produce a total deterministic error at the final output of the chain of operations ( ). In the present invention, truncation is used in place of rounding after each operation by simply not rounding in software. Recognizing that all the bias introduced by replacing rounding with truncation results in a single deterministic error at the final output, in the present invention the total bias ( ) is predetermined and subtracted from each data sample of the final output sequence.
