INTERPOLATION IN INCREMENTAL MEASUREMENT |
摘要 |
<p>An interpolation process is described for use with an incremental position measuring device which produces a periodic analog output signal. The output signal is digitized and then applied as an input to a digital computer programmed to calculate the interpolation value of the signal. In the preferred embodiment the computer is also programmed to apply a number of corrections to the digitized signal prior to interpolation.</p> |
