Abstract
PURPOSE: To make it possible to remove cross talk excellently by using a coupled circuit which includes a phase inversion method, amplitude adjustment method and phase-shifting method.
CONSTITUTION: Magnetic heads are represented by Ha and Hb, and inverters 9 and 10, amplitude adjustment circuits 11 and 13 and phase shifting circuits 12 and 14 constitute coupled circuits Ca and Cb. Then, circuits 11 and 13 has a function of setting easily the amplitude of a signal transmitted through circuit Ca or Cb and that of increasing as required the amplitude of the signal as the signal increases in frequency. Further, phase shifting circuits 12 and 14 provided with characteristics that phases of the signals transmitted through circuits Ca and Cb are shifted as required. The circuit with the above-mentioned function can be composed of a parallel circuit of a resistance and capacitor and a variable resistor. Then, the cross- talk removal effect can be improved by adequately setting various constants of the above-mentioned circuit.
