CARRIER DETECTING CIRCUIT IN DATA COMMUNICATION SYSTEM

摘要

The a circuit for detecting a carrier of the data in order to sense if the data transmission is completed, a sensor for sensing if the data are received; a counter for counting the time when the data receiving is not sensed in the sensor to detect the lapse of the regulated time; and a detector for sensing if the data are received from the sensor, and generating a carrier detecting signal indicating if the data carrier is detected by the output of the counter.
