发明名称 Device for compensation of transfer functions
摘要 PCT No. PCT/SE80/00200 Sec. 371 Date Apr. 3, 1981 Sec. 102(e) Date Mar. 27, 1981 PCT Filed Aug. 1, 1980 PCT Pub. No. WO81/00452 PCT Pub. Date Feb. 19, 1981.The present invention is a device for compensation of electric transfer functions of electric or electronic sensors (G), detectors, instruments or four-poles. According to the invention, the signal from the unit (G) to be compensated is connected to a differential amplifier (D) with a feed-back network (Z) having a transfer function that is substantially the same as the transfer function to be compensated. The compensating device has a transfer function that approximately is inverse to the transfer function of said sensor (G). The signal that the sensor senses and that is distorted by the nonlinear transfer function of the sensor is then restored. The feed-back network can either be passive or consist of electrically controllable active filters.
