Abstract
PURPOSE: To detect the framing code signal by detecting the arrival of the code signal featuring the specified pattern by means of the output signal which is produced when the address of the code signal coincides with the address corresponding to the specified pattern.
CONSTITUTION: The code signals received are supplied in sequence to the shift register, and the code signals of the bit number corresponding to the specified pattern are drawn out in sequence and in parallel to each bit. These drawn-out code signals are supplied to the memory set up previously in such a way that the output signal may be produced only at the address that corresponds to the specified pattern. And when the address of the supplied code signal coincides with the address corresponding to the specified pattern, the arrival of the code signal featuring the specified pattern, is detected via the output signal. Thus, the framing code signal can be detected
