A method is presented for compensating in real-time for the transfer function of a data acquisition channel by means of a digital IIR (infinite impulse response) filter. The theory behind the measurement is developed, the experimental setup is described, and the estimation results are presented. Real-time experiments have shown that correction within a long-term error of +or-0.01 dB on the flatness of the amplitude and 0.1 degrees on the linearity of the phase is possible.<>
