Patent ID: 8600694

Claim:
A method for treatment of a noisy temporal digital signal (y k ) with digital pitch (k), said noisy temporal digital signal (y k ) corresponding to an initial analogue signal (s t ) after it has been conditioned by a conditioning chain, with said initial analogue signal (s t ) including at least one pulse representative of information on radiation ( 30 ) coming from a radiation source, with this radiation ( 30 ) and the at least one pulse exhibiting an energy distribution, wherein a non-noisy estimated digital signal (s k ) is determined, by a computing unit, from the noisy temporal digital signal (y k ) by using a state model representative of said conditioning imposed by the conditioning chain, and wherein the state model includes a Markov variable (r k ) to be estimated, said Markov variable (r k ) being able to take at least two values, each of the at least two Markov variable (r k ) values being associated with physical characteristics of a corresponding model pulses, with each corresponding model pulse constituting a possible representation, or at least closely approaching a possible representation, of the at least one pulse in the initial analogue signal (S t ).
