device for measuring the rise time of signals from interference by noise, radiation detectors or x x x x x x x

摘要

The invention relates to a device for measuring the rise time of the electronic component of a signal disturbed by the electronic noise, the signal / noise ratio is mediocre. It comprises: - a differentiator circuit (c12, c11) comprising at least one resistor (r) and a capacitor (c) forming a - a high pass filter for filtering out the parasitic noises of low frequency of the signal from the detector; - a discriminator circuit (c21, c22) comprising a comparator (k) in order to carry out a comparison between the filtered signal coming from the differentiator circuit and an offset voltage chosen as a function of the noise level in this way, the signal from the detector.
