  • Digital filter having a substantially equal number of negative and positive weighting factors
    Patent number: 5928314
    Abstract: In a digital filter in which coefficients are realised using power of two weighting factors, it can occur that due to rounding errors the output signal shows some inaccuracies. By decomposing the filter coefficients into powers of two in such a way that most powers of two have a counterpart with an opposite sign, the rounding errors tend to cancel, resulting in a more accurate filter.
