Abstract

PURPOSE:To secure the simultaneous perfromance for the phase decision of the bridge output signal and the digital coding, by using the pulse which is synchronized with the lamp signal with the double cycle for the control signal of the up-down counter as well as for the exciting signal of the bridge circuit. CONSTITUTION:The oscillation output signal of reference oscillator 1 is divided by frequency divider 2, and the division output is supplied to lamp signal generator 3. The lamp signal is supplied to voltage comparator 4 and then converted into the high and low pulses in the case of the higher and lower potentials than the output signal of amplifier 9 respectively. Gate circuit 5 sends the output signal of reference oscillator 1 to up-down counter 6 only when the output pulse of comparator 4 is high. At this instant, both the excitation signal to be applied to bridge circuit 8 and the up-down control signal of counter 6 are made to synchronize with the lamp signal by frequency divider 2 along with application of the pulse having the double cycle compared with the lamp signal.
