Description: |
| Abstract:
A digital to analog converter is disclosed which produces analog signals having a phase relationship therebetween which is a function of digital input signals. The digital to analog converter is typically used in control systems for commanding or measuring the motion of a movable element. The converter contains variable modulo counters which permit a scaling of the signals during the conversion process. Consequently, input signals having different resolutions may be programmed in a control system; and the converter will produce command signals for moving the element in accordance with the input signals. Similarly, in a measuring system, the converter may be used to obtain a readout of the motion of the element according to any desired resolution. |
