DISTRIBUTED SAMPLE SCRAMBLE SYSTEM

摘要

PURPOSE: To scramble distributed samples with a simple circuit configuration. CONSTITUTION: A scrambler outputs data scrambled by adding a binary output from a 1st shift register generator 1 to input data with an output means and a 1st sampling means 2 samples the binary output at a time interval that is not constant. A descrambler samples a binary output from a 2nd shift register generator 5 with a 2nd sampling means 4 at the same time interval by the 1st sampling means 2, and a comparator means 3 compares the outputted sample with the sample from the 1st sampling means 2. Then a correction means 6 gives a correction signal to the 2nd shift register generator 5 depending on the comparison result and an output of the 2nd shift register generator 5 and the scrambled data are added to each other.
