Abstract

PURPOSE:To clear a PAM multiple signal in a signal cable by earthing the leakage component of the PAM multiple signal through switching control. CONSTITUTION:At the leading edge of each clock signal 7 generated by clock signal generator CLK, monostable multivibrator MM operates to generate clear signal 8. This signal 8 is led to switching elements Q1 and Q2, which turn ON by each signal 8. Since this turn-on timing agrees with the transmission timing of the trailing edges of respective sampling signals 5', 5'' ... of PAM multiple signal 5, crosstalk components 6, 6' ... are bipassed to the ground with the both ON, so that PAM multiple signal 5 in this signal cable will be cleared during this period.
