Abstract
PURPOSE: To enable stable displaying to be accomplished by so constituting a time constant circuit and a time constant correcting circuit that the output signal becomes only in one direction of increase or decrease despite the existence of an increase or decrease in the original level signal.
CONSTITUTION: When the level difference of the level signal S1 and the output signal S2 of a time constant circuit 2 is within the specified width, the time constant of the time constant circuit 2 is made the first time constant and when it is other than the specified width, the time constant of the time constant circuit 2 is made the second time constant and the output signal S2 of this time constant circuit 2 is let to follow up the level signal S1. Said output signal is then displayed. This enables the device to be so constituted that the output signal S2 following up the level signal S1 and having less undulations than the level signal S1 is obtained by the first time constant. In addition, the time constant correcting circuit 3 causes the output signal S2 of the time constant circuit 2 to follow up to the level signal S1 fast at the operation starting of the time constant circuit 2 or at the abrupt changing of the level signal S1, hence stable displaying may be accomplished.
