Abstract
PURPOSE: To arrange so that the DC component may be removed in a short period of time by switching, during a prearranged period, a time constant for a differentiation circuit which removes the DC component.
CONSTITUTION: The first switch SW1 is set in ON position, and the second switch SW2 is charged over to the contact point (a) side. When measurement is started, the second switch SW2 is turned to a contact point (b) side, selecting the second differentiation circuit. After the elapse of time so many times of C.R2 following the start of measurement, the switch SW2 is set in neutral position, selecting the third differentiation circuit. As a result, it is possible to remove the DC component in a brief period of time.
