A filter with a trapezoidal weighting function is the optimum one when both noise and variations in the charge collection time are present, A trapezoidal filter was realized by a time-variant (gated filter) system. This paper presents the results obtained with large germanium detectors at high rates and higher energies, showing that trapezoidal filtering is essential for good resolution in this case.
