Abstract
PURPOSE: To number subblocks by exercising control so that a reference signal for generating a window pulse for extracting the 1st block-synchronizing signal has a constant phase relation to a reproduced signal.
CONSTITUTION: Every time some samples are extracted from an input digital signal, a subblock is generated and block-synchronizing signal is added to every subblock; and a certain number of subblocks constitutes a main block and prescribed signal processing is performed for every subblock and main block. Then, the 1st subblock-synchronizing signal of the main block is extracted 93 and servo loop 80 exercises control so that this extracted signal will have a constant phase relation to reference signal REV whose repetitive period is equal to that of the main block in order to generate a window pulse.
