Abstract : The patent describes a digital-to-analog converter having digital angular data inputs applied to integrated switches to cause predetermined switching in circuit with resistance ladder networks of R and 2R values. It provides sine and cosine approximation analog voltage functions representing the digital input signals some of which digital signals control quadrant switches to produce quadrant reference phase relationships and the remainder of such control analog signals to provide amplitude scaling to drive a synchro mechanism in angular correspondence with the digital angular data inputs.
