Automatic multiplex delay system

Abstract

Abstract PURPOSE:To set automatically the delay of a transmission line by correcting the delay time of the transmission line of multiple constitution through firmware during initialization, and holding data on it. CONSTITUTION:A delay correcting circuit 103 receives input signals from highways 105a-108a and judges how long the highway input signals need to be delayed on the basis of memory data, thereby outputting highway output signals to highways 105b-108b. When initializing operation (POW ON RESET) is performed, a pilot pattern signal outputted from the delay correcting circuit 103 is monitored by a microprocessor 102 and memory contents are updated until a pilot pattern is outputted to the highways 105b-108b at the same time. The delay correcting circuit 103 varies the delay time successively when the memory contents are altered.
