Abstract
The present invention discloses a device for converting a digital input into an analogue output, comprising means for generating a binary pulse signal in dependence on said digital input, a filter for filtering said binary pulse signal to obtain said analogue output where the level of the analogue output depends on the relation of high and low level pulses of the binary pulse signal during a period and the precision of the analogue output depends on the number of binary pulses during the period. The high and low level pulses in the binary pulse signal are spread through said period.
