REPEATER AND ANALYZING METHOD FOR DETERIORATION IN PERFORMANCE

摘要

The present invention relates to a repeater, and more particularly, to a repeater capable of analyzing performance degradation itself. The repeater according to an embodiment of the present invention includes a digital signal processor for generating a first digital test signal, outputting the first digital test signal to a first link, and analyzing the strength of a second digital test signal to determine performance degradation of a second link; a digital-to-analog conversion unit formed on the first link to convert the first digital test signal into a first analog test signal; a signal splitter for coupling the first analog test signal and outputting the second analog test signal to the second link; and an analog-to-digital conversion unit formed on the second link to convert the second analog test signal into a second digital test signal and output it to the digital signal processor.
