Description
операционного усилител 1, с выхода которого сигнал через цепь обратной св зи, выполненную на элементах 4-10, подаетс на инвертирующий вход этого же усилител 1. За счет обратной св зи формируетс передаточна характеристика компенсатора, обратна характеристике передачи канала магнитной записи. Сигнал с выхода первого операционного усилител 1 посылаетс также на формирователь 11 частотных полос. Полосные сигналы с выходов формировател 11 подаютс на выпр мители 12. Максимальный сигнал с выходов выпр мителей 12 выбираютс блоком 13 и формируютс в сигнал управлени , который подаетс на дополнительный вход антилогарифмического усилител 7, в котором осуществл етс коррекци передачи компенсатора , что уменьщает искажени преимущественно в той полосе, в которой спектральна плотность имеет максимальную величину.operational amplifier 1, from the output of which the signal is fed through the feedback circuit, made on elements 4-10, to the inverting input of the same amplifier 1. By means of feedback, the transfer characteristic of the compensator is formed, inverse to the transmission characteristic of the magnetic recording channel. A signal from the output of the first operational amplifier 1 is also sent to the frequency generator 11. The band signals from the outputs of the imaging unit 11 are fed to the rectifiers 12. The maximum signal from the outputs of the rectifiers 12 are selected by the unit 13 and are formed into the control signal, which is fed to the auxiliary input of the antilog amplifier 7, which compensates for the transmission of the compensator, which reduces the distortion mainly in the band in which the spectral density has the maximum value.
Таким образом, изобретение позвол ет компенсировать нелинейные искажени в расн1иренном днапазопе частот.Thus, the invention makes it possible to compensate for the non-linear distortions in the distant frequency gap.
