摘要
FIELD: data carriers.;SUBSTANCE: in response to control reading signal received at amplifier input, on output of this amplifier output signal is produced, signal is then formed, reflecting difference between output amplifier signal and support signal. First compensation signal is generated, absolute value of which is proportional to absolute temperature, and second compensation signal, absolute value of which does not depend on temperature during forming estimation signal first compensation signal is summed with signal, reflecting said difference, or is subtracted from it dependently on second compensation signal.;EFFECT: higher precision.;4 cl, 7 dwg
