Therefore it is necessary to use an si-correction filter in addition to a low-pass filter for the errorless signal reconstruction. Six easy to realize si-correction filters that suffice most practical requirements are presented. Besides that, for each of the six filters an all-pass filter was designed. This all-pass can be inserted behind the si-correction filter if the group delay equalisation for a low-pass and the si-correction filter cannot be performed with a single network.deall-pass filtersdigital-analogue conversionpassive filtersD/A converteroutput signalSi-functionSi-correction filterlow-pass filtererrorless signal reconstructionall-pass filtergroup delay equalisation621journal article
