发明名称 INTERFERENCE DETECTION SYSTEM
摘要 <p>PROBLEM TO BE SOLVED: To provide an interference detection system, in which the conditions of signal leakages from other transmission line laid in a physically approximate place can be recognized easily, at the user side of transmission line. SOLUTION: The interference detection system is provided between a transmission line and a terminal and detects interference with a signal on other transmission line, employing a different signaling system. The interference detection system comprises a means (300) for detecting the power spectrum of signal components, having specified frequencies (f1, f2) on the transmission line, a means (310) for generating output information, depending on a power spectrum detected by the power spectrum detecting means within a specified time period, and a means (320) for displaying the interference level, depending on the output information.</p>
