<p>PURPOSE:To attain the correction of a cell when abort of plural cells and cell misdistribution exist continuously in mixture by setting tentatively number of aborted or inserted cells with a tentative correction means and correcting the setting according to a dissident output of a 2nd discrimination means. CONSTITUTION:A tentative correction pattern length setting circuit CLE is provided as a correction length tentative setting means setting tentatively number cells inserted or aborted by a tentative correction pattern setting circuit TCE and a tentative correction pattern length control circuit CLCON is provided as a means correcting the setting by the tentative correction pattern length setting circuit CLE according to a dissidence output CO2 of a cell number collation circuit SNC 2. Then the correction pattern length and the correction pattern over plural cell periods are set and the correction pattern length and the correction pattern are repetitively revised till the correct correction pattern is obtained based on the result of discrimination of the adaptability of the correction pattern. Thus, the limitation due to a form of abort and mis- distribution of a corrected cell is avoided and complete correction is always attained.</p> |
