A method, digital circuit system and program product for reducing delta-I noise in a plurality of activity units connected to a common DC-supply voltage. In order to smooth the fluctuations (delta-I) of a total current demand I, and a respective resulting fluctuation of the supply voltage, a signalling scheme between said activity units and a supervisor unit which holds a system-specific "database" containing at least the current demand of each activity unit device when operating regularly. Dependent of the quantity of calculated, imminent delta-I a subset of said activity units with a respective current I demand is selected and controlled, for either temporarily delaying their beginning of activity in case of an imminent supply voltage drop, or temporarily continuing their activity with a predetermined, activity-specific NO-OP phase in case of an imminent supply voltage rise.
