Abstract
PURPOSE:To remove interference between codes by adjusting the gain of an emphasis circuit at an equivalent frequency according to whether each correlation result under monitoring is greater or less than a reference voltage. CONSTITUTION:When interference between codes occurs in the output of adder 5, output levels of peak voltage detecting circuits 81, 82...8N are over or short in the reference level. If those output levels are greater than reference voltage Vref, outputs of control circuits 101, 102...10N decreases, and consequently gains of emphasis circuits 91, 92...9N decreases. On the other hand, when output levels of peak voltage detecting circuits 81, 82...8N are less than reference voltage Vref, outputs of control circuits 101, 102...10N increases, so that gains of emphasis circuits 91, 92...9N may be increased. Under such control, the interference between codes is removed by the outputs of emphasis circuits.
