Method of and arrangement for generating pulses of an arbitrary time relation during immediately successive assumed pulse intervals with a very high accuracy and time resolution

摘要

The present invention is directed to a method of and and apparatus for continuously generating desired pulses during assumed successive desired pulse intervals with a very high time resolution by digitally predetermining the time values related to the start of the desired pulse intervals. These time values are divided into coarse and fine time rasters and coarse pulse intervals are generated from the assumed desired pulse intervals. The coarse pulses in the coarse time raster are generated from the desired pulses and each coarse pulse start and coarse pulse end, respectively is associated with a coarse pulse correction value. By adding the coarse pulse interval correction value to the coarse pulse correction value for the start and the end of the coarse pulse, respectively, a sum correction value is obtained and divided into a partial value associated with the fine time raster. The partial value of the sum correction value is used as a control value for a selected time delay for the coarse pulse edge shifted.
