  • Switching arrangement for the transformation of digital angles into analog sine-and/or cosine values
    Patent number: 3974498
    Abstract: A switching arrangement for generating sine and/or cosine function analog outputs in response to input digitally coded angle values where a correspondingly coded digital to analog converter is compensated by means of a correction circuit comprising a resistance network controlled by switches responsive to the input angle. Preferably the correction circuit is interposed between a constant voltage source and the converter so that the reference voltage supplied to the converter is precompensated to achieve sine and cosine output values of a desired precision.
