Abstract: PURPOSE: To prevent information from being lost by recognizing a sample pattern through a decoder and activating the read of the final sample in the next term from the first sample in a term determined by a receiver concerning the sample of which this pattern is read. CONSTITUTION: The samples read from a data stream at suitable intervals are sent to 5 pieces of double-step shift registers 54. The latest sample is stored in a step 56 and the oldest sample is stored in a step 58. The respective samples are separated in the 1/5 term of a data bit term. Since the pattern is recognized by logic elements 60, 62, 64, 66 and 68 composed of six wide AND gates having transducers at three position of an input part, the transition from Low to High is detected. By recognizing the pattern, phase information is applied and corresponding to this information, the sample of an object to be read can be seletected.
