DIGITAL-TO-ANALOGUE CONVERSION |
摘要 |
The converter incorporates a transversal filter. The filter delays are implemented in digital form prior to conversion into analogue signals (preferably using switched capacitor techniques). One form of switched capacitor converter (with or without filtering) employs a single capacitor, common to a plurality of bits, appropriate weighting of the bits being achieved by controlling the switching.
