Abstract

In order to be able to perform a measurement of the run time of an electrical impulse in a position sensor through a single slow timed timing generator, while still capable to achieve a high precision of the measurement result, the entire run time is determined, so that the number of the completely performed system timings is counted as a coarse time value, and the fractions thereof are counted as a fine time value, in which the electrical impulse is started at a fixed point in time of the system timing, e.g. at the beginning of the timing, and the difference value is measured between the end of the coarse time interval and the arrival of the wave as a fine time interval, which is then digitized and computed with the coarse time value.
