Abstract: A compensating current is applied at one or more points in a signal processing path to compensate for one or both of a dark or offset current present in an input signal. In certain implementations, the dark or offset current is present in a signal generated by a photomultiplier device. The dark or offset current may be monitored in an output of the signal processing path and, the monitoring being used to determine how much compensation is needed in the signal processing path and to allocate where in the signal processing path the compensation current will be applied.
