Abstract
An electronic apparatus for automatically detecting the length of network transmission lines. The electronic apparatus essentially comprises a detection device, an analog/digital (A/D) converter, a microprocessor, a frequency compensator and a transmission network line, such as an RJ-45 network transmission line. The electronic apparatus utilizes the detection device to detect a frequency response of the reference signal for generating detection signals and converts the detection signals into digital signal. Thereafter, the microprocessor outputs a control signal so that the frequency compensator, comprising resistors and capacitors, makes up for the video frequency according to the control signal. As a result, the optimum video frequency is generated to display a clear image on a monitor for the benefit of the operation.
