Abstract
PURPOSE:Errors are reduced by changing the two sets of reactances selectively changed over to a resonance circuit of an oscillator in relation to mechanical displacements and converting two kinds of frequency signals to pulse widths corresponding to the displacements by means of an up-down counter and logic circuit.
