A system for the suppression of noise and its variations for the detection of a pure signal in a measured noisy discrete signal. The system measures a counting rate N2 in a signal channel and a counting rate N3 in a reference channel, evaluates the estimation value lambda E of the ratio lambda between the mean noise levels in the channels and evaluates the associated false detection probability I as a function of (N2, N3 lambda E). The system then performs a comparison of I with at least one information threshold Im, each associated with a predetermined false detection level. Comparison can take place indirectly on a function of the probability and can use tabulated values. The system has particular application to the detection of corpuscular radiation.
