An imaging system includes at least one radiation generating component (210) that alternately emits different radiation that traverse an examination region and a common detector (214) that detects radiation that traverses the examination region and generates a signal indicative thereof. Pulse generating circuitry (304) generates a pulse train, including a plurality of pulses, with a frequency indicative of the signal for the at least one radiation generating component (210) for a sampling interval. Processing electronics (220) determine an approximation of the signal for one of the at least one radiation generating components (210) for the sampling interval based on a number of pulses in the pulse train for the sampling interval and charge of the pulses in the pulse train.
