摘要：

Processing of 1/f-noise by suboptimal filters in detector charge measurements is considered. The achievable values of equivalent noise charge are compared to those provided by the optimum filter. Some aspects of filters processing 1/f-noise, like the degradation in the accuracy of charge measurements due to a bipolar or a unipolar, flat-topped weighting function are described. Several conclusions are expected to be useful in the design of analog processors for radiation detectors when the front-end 1/f-noise is not negligible.
