Signal Processor Recovery Time Effects on Photon Counting Accuracy, Observed Counts, and True Events

The response time of the signal processor is examined from the standpoint of the "trade-offs" that can be made by the experimenter in defining the data accuracy in terms of the signal processor recovery time, observed counts, standard deviation, and required number of data scaler bits. Curves are shown which for different values of recovery time, the true event rate can be determined at an observed count rate. Other curves show the relationship between data scaler bit levels and resultant data accuracy at different standard deviations.
