ABSTRACT:
The linear signal output range of a rotary transformer type device, such as a sine/cosine synchro, is considerably extended beyond its normal 45.degree. linear range by electronic circuit means. Specifically, the electronic circuit means utilizes the sine signal, which is generally linear from 0.degree. to 45.degree., as a portion of the output signal and utilizes a resultant signal computed from the cosine signal, which is linear from 45.degree. to approximately 135.degree. for the remaining portion of the output signal.
