FIELD: technology for transferring signals, possible use for correcting signal processing circuits transfer characteristics. ^ SUBSTANCE: method for preliminary correction of signal processing circuit transfer characteristic includes receiving difference between output signal of signal processing circuit and input signal of preliminary correction means, gradient of aforementioned difference is approximated on basis of aforementioned produced difference and approximation of aforementioned transfer characteristic and control values of aforementioned signal of preliminary correction means are renewed on basis of aforementioned approximated gradient. Device meant for preliminary correction of transfer characteristic of signal processing circuit contains comparison means, meant for producing difference between output signal of signal processing circuit and input signal of preliminary correction means, means for approximation of gradient of aforementioned difference and for approximation of aforementioned transfer characteristic and renewal means, meant for receiving control values. ^ EFFECT: increased precision of signal processing circuit signal transfer. ^ 2 cl, 5 dwg |
