Abstract
Abstract AN ELECTRONIC ANGLE ENCODER WHICH EMPLOYS INTERCONNECTED SINE AND COSINE CHANNELS TO CONVERT A RESOLVER OR SYNCHRO ANALOG ANGLE SIGNAL INTO A BINARY DIGITAL SIGNAL. THE INPUT SINE AND COSINE SIGNALS ARE STORED IN THE ENCODER AND SUBSEQUENTLY CHANGED IN BINARILY DININISHING STEPS TOWARD A KNOWN REFERENCE LEVEL. AFTER EACH STEP, THE STORED VALUES ARE COMPARED TO A REFERENCE. THE RESULT OF THIS COMPARISION CONSTITUTES THE DIGITAL REPRESENTATION OF THE ORIGINAL ANGLE.
