ABSTRACT A digital to analog resolver converter uses a digital to analog converter to convert a part of the digital input to a corresponding analog angle value. This analog angle value is applied to since and cosine function gen- erators which use the equations of chords to approximate the value of the sine and consine functions in one octant. Bits of the digital input are used to select slope values from the chord equations for approximating the sine and cosine of the analog angle value. The digital to analog resolver converter uses the minimum number of precision resistors to generate the sine and cosine slope and inter- cept values for the equations of a given number of approx- imating chords.
