Abstract

PURPOSE:To read the information of a sense signal surely without being affected by a noise signal by reading the output of a voltage comparator by using a predetermined strobe signal in a memory device etc. CONSTITUTION:An input signal IN is formed of a sense signal and a noise signal. A control signal CONT is applied only for the predetermined time from the peak phase time corresponding to the information ''1'' on the sense signal and over the period T of the noise signal component. Then, the output of a DC reproducing circuit 2 is made to consist of the amplified output of the signal IN moved in parallel in a negative direction with the rising point of the signal CONT as 0V, and the output of the voltage comparator 3 corresponds to the information ''1'', ''0'' within the period T and to information ''1'' after the period T. Only during the period when a strobe signal STR is applied to one end of an AND gate 5, a read output OUT is obtained. The phase and pulse width of the signal STR are so selected that the output of the comparator 3 around the period T time of the noise signal from the rise of the signal CONT comes within a high level range.
