Title:
APPARATUS FOR PROCESSING SIGNALS OF PULSE ENCODER
Document Type and Number:
WIPO Patent Application WO/1989/001607
Kind Code:
A1
Abstract:
An apparatus for processing signals of a pulse encoder electrically processes output signals from a signal generator to improve the resolution of the encoder. Sine wave signals and cosine wave signals supplied from the signal generator are converted into digital signals through first and second A/D converters, respectively, and are supplied to a signal conversion means which produces an analog amplitude level and position data depending upon the outputs of the first and second A/D converters. Thus, the circuit constitution ca be simplified, the space occupied by the apparatus can be reduced, and the intensity of signals supplied from the signal source can be confirmed.
