CIRCUIT FOR RESTORING BIT TRANSMITTED WITH ASYNCHRONOUS SIGNAL, METHOD FOR DETECTING SYNCHRONOUS BURST, METHOD FOR CONTROLLING BIT RESTORATION ERROR, AND METHOD FOR DETECTING SIGNAL WITH HIGH FREQUENCY LOSS

摘要

PROBLEM TO BE SOLVED: To restore bits which are transmitted with an asynchronous signal when a transmit signal having a synchronous burst synchronously is processed and readjusted. ;SOLUTION: The circuit for restoring the bits transmitted with the asynchronous signal includes a 1st comparator 10 which compares the level of the asynchronous signal with a 1st threshold value Vref adjusted as a function of the output of a 1st comparator 10 during the synchronous burst of the asynchronous signal and at least one 2nd comparator 14 which compares the level of the asynchronous signal with a 2nd threshold value VrefH correlating with the 1st threshold value.;COPYRIGHT: (C)1996,JPO
