Now, when S2 is ON, the reference voltage Es of a reversed polarity from Ex is connected, and is integrated towards the zero voltage direction. When the integrated output becomes zero, a comparator will activate and the integration will be stopped. The time brings it back to zero is Tx. A formula is established as the relationship of those periods as blow. As Es and Ts are predetermined values, a digital value proportional to the input can be acquired by measuring Tx with a pulse counter. In the integral method to the left, the + half cycle and the – half cycle offset the superimposed noise effectively. Therefore, when the input integral time is more than doubled of the power...
