Abstract

PURPOSE:To obtain the characteristics equivalent to those when a differentiating element is provided in a feedback circuit by employing a differentiation preference system. CONSTITUTION:A normally open switch SW which is turned on by the limit signal from an output limiter circuit L is connected across a resistance R constituting a differentiating element D, and the output terminal of an operational amplifier A2 and a load input terminal are directly connected. When a step input enters from an input terminal 10 and said step input attains the limit point having been set in the output limiter circuit L, feedback current flows from the output of the operational amplifier A1 to a summing point Sp through the output limiter circuit L. At the time when the output limiter circuit L operates, the normally open switch SW goes on to reset the charging voltage of the differentiating element D.
