Abstract
PURPOSE: To always secure the constant amplitude of the demodulated signal, by detecting the peak value of the demodulated signal and then giving the negative feedback to the detection signal.
CONSTITUTION: The outputs of demodulating circuits 10a and 10b are sent to inverse amplifiers 13a and 13b via amplifiers 9c and 9d each. Here amplitude detecting circuit 14 detects the sum of the highest negative voltage among the voltage delivered from amplifiers 9c and 9d plus 13a and 13b each and the voltage obtained by giving the 1/21/2 multiplication to the general sum of the negative voltage. And then this detected voltage is delivered in the form of the amplitude of the voltage delivered from amplifiers 9c and 9d plus 13a and 13b each. Accordingly, the outpt of adder circuit 12 increases if the detected voltage decreases. On the contrary, the output of circuit 12 decreases if the detected voltage increases. As a result, the gap varies between the stator and the rotor of the inductosyn, and then the mutual inductance may change among print conductors 7a, 7b and 7c each. But the variation can be avoided for the amplitude of the voltage delivered from amplifiers 13a and 13b.
