Abstract:

We demonstrate how to discriminate pulses by computing the ratio of a pulse’s peak amplitude to its integrated area. This approach, known as Pulse Shape Discrimination (PSD), is often used in nuclear or radiation detection to distinguish between pulses of different decay times. For exponential pulses, the ratio of amplitude to area is directly linked to the decay constant, allowing us to classify signals based on their shape.
