Abstract
Common causes of resolution degradation are discussed for low and high count rates. Previous works have presented signal/noise versus shaping networks for Johnson noise and 1/f2 noise. Equations are derived here to include l/f noise, which is found to be significant. Results are presented for peak-height change versus input rise time for different shaping networks. For high count rates, the need for an amplifierwithlongtime constants and the use of a baseline restorer are discussed. A restorer and deadtime gating circuits are presented, along with experimental results.Keywords
