Process for the filing of measurement signals which are obtained by scanning a n4 incremental with a unit for survey and apparatus for implementing this process

摘要

A computer (5) executes appropriate corrected computations on digital values corresp. to the analog signals obtained by scanning. The computer calculates a desired sequence of signalsand uses it for interpolation. The computer is calibrated below a given scanning speed and periodically and with the max. of the first signal train or digital signal. The max. and min. are used by the computer to calculate the d.c. component of the signals to eliminate this component. Correction factors are then determined for the signals
