A device for compensating a delay τ suffered by a first periodic signal ref(t) during propagation between a first and second end of a first transmission connection, comprising at least:- first means able to generate a second signal ref(t+τ) corresponding to the first signal ref(t) the phase of which is advanced by a time equal to the delay τ,- second means able to generate, from a third signal ref(t−τ) obtained at the second end of the first transmission connection and corresponding to the first signal ref(t) the phase of which is delayed by the delay τ, and from the second signal ref(t+τ), a fourth signal in phase with the first signal ref(t).
