Abstract:
A method for generating a time mean value-free binary signal (OUT) from an input signal (IN), comprising the steps of:generating a first binary signal (O, O4) from an input signal and a control signal;filtering the first binary signal (O, O4) through a first filter (8, 48) with substantially low pass characteristic, generating a first filtered signal (S, S4);filtering a time mean value-free reference signal (J, J4) through a second filter (7, 47) with substantially low pass characteristic, generating a second filtered signal (FJ, FJ4); andgenerating the control signal (C, C4) based on a difference signal between the first filtered signal (S, S4) and the second filtered signal (FJ, FJ4), said control signal being substantially proportional to the sum of the difference signal multiplied by a first constant and a second constant multiplied by the integral of said difference signal;wherein the first filter (8, 48) and said second filter (7, 47) are substantially equal, and said time mean value-free binary signal (OUT) is constituted of said first binary signal (O, O4).
