Abstract
A radiation detector emits a signal containing pulses produced by each radiation event being detected. The pulses tend to decay and may overlap the pulse from a subsequent radiation. In order to prevent such pulse overlap a circuit is provided to clip the signal pulses. The circuit incorporates an analog delay line which produces a delayed, inverted and attenuated reflection of the original detector signal. The reflection signal is combined with the original detector signal to cancel remnants of each pulse lasting longer than the predefined delay period.
