The invention relates to a switchable interpolator for incremental measuring systems for distance and angle measurement, with the aim of reducing the circuit complexity and improving the adaptability of the measuring systems to different scales. The object is, above all, to achieve different interpolation factors with one interpolator. The switchable interpolator comprises mink-times interpolators which are logically combined by logic circuits and connected to a counting direction and edge evaluating device. An adjusting device for adjusting the interpolation factor is provided. The logic circuits comprise logic circuits known per se such as AND gates, or EXCLUSIVE-OR gates, inverters and NAND gates operating in various functions. <IMAGE> |
