1. A device for identifying an electronic or electromechanical system, comprising:

  • a noise generator for generating a noise signal (uk), intended to generate the noise signal at the input of said system;

    a one-bit analog digital converter, to which an output signal (sk) of the system is intended to be applied;

    an estimation device for carrying out an estimation (ĥ

    ) of the impulse response of said system comprising;

    first calculation means to perform an iterative calculation of a plurality of nh (with nh being an integer) elements (J0, . . . , Ji, . . . , Jnh−

    1
    ) of a given criterion J, each element including at least one correlation term between said signal output from said converter and said noise signal;

    means for making an estimation (ĥ

    k) of the output of said system with the aid of said estimation of the impulse response of said system, said means comprising a second calculation means to apply, to the calculated elements (J0, . . . , Ji, . . . , Jnh−

    1
    ) of said given criterion J, a passage function f predetermined as a function of the noise signal (uk) transmitted at the input of said system, and such that;
