A method for processing a noisy digital time signal yof digital pitch k, corresponding to an initial analogue signal safter being conditioned by a conditioning chain. The initial analogue signal sincludes at least one pulse representing information concerning at least one radiation from a radiation source, the radiation and the pulse having an energy distribution. The method includes the determination of a non-noisy digital estimation signal sfrom the noisy time signal yby using a state model representing the conditioning imposed by the conditioning chain and in that the state model includes a Markovian variable rto be estimated whereof at least two values are associated with physical characteristics of at least two typical pulses constituting a possible representation, at least approximate, of the pulse in the signal s.
