PURPOSE:To suppress an increase in the accumulation of all jitters by converting jitters which are accumulated in proportion to the number of repetitions on a repeating transmission line into random jitters. CONSTITUTION:Repeating transformers (T1-T30) 9 each has the start 1 and end 2 of winding. The direction of the primary winding of each transformer 9 is opposite between an odd-numbered and an even-numbered channel. Consequently, adjacent noises having low frequency components superposed upon an input signal are out of phase with each other and become random without added behind an encoder 10. Jitters generated on the repeating transmission line turn into random jitters proportional to the number N of repetitions raised to one fourth to suppress a cumulative increase of jitters on the repeating transmission line. |
