摘要： PROBLEM TO BE SOLVED: To provide a small-size and inexpensive signal detector simply used for noise detection as a development tool for device development engineers. SOLUTION: On power source lines 21A and 21B connected to a power source input terminal T1, a signal suppression filter 22 for suppressing high-frequency signals included in a power source voltage and a signal separation filter 23 for hindering the transmission of the high-frequency signal are provided in series while a high-frequency signal included in the source voltage is outputted from signal output terminals T3 to T5, the source voltage being across a power source output terminal T2 and the separation filter 23. The high-frequency signal from a power source can be blocked by the suppression filter 22 and by the separation filter 23, making it possible to remove the effect of power source noise on a measurement system. Since the separation filter 23, positioned between the suppression filter 22 and the output terminal T2, hinders a high-frequency signal occurring in an apparatus 3 under measurement from being absorbed by the suppression filter 22, a signal detection level at the output terminals T3 to T5 can be prevented from lowering.

摘要翻译：要解决的问题：为了提供简单用于噪声检测的小尺寸和廉价的信号检测器，作为设备开发工程师的开发工具。解决方案：在连接到电源输入端T1的电源线21A和21B上，用于抑制电源电压中包括的高频信号的信号抑制滤波器22和用于阻止电源电压的传输的信号分离滤波器23 串联提供高频信号，而从信号输出端子T3至T5输出源电压中包括的高频信号，源电压跨过电源输出端子T2和分离滤波器23.高频信号来自电源的信号可以被抑制滤波器22和分离滤波器23阻挡，使得可以消除电源噪声对测量系统的影响。由于位于抑制滤波器22和输出端子T2之间的分离滤波器23阻碍在测量的装置3中发生的高频信号被抑制滤波器22吸收，所以在输出端子T3至 T5可以防止降低。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To suppress emissive noise which is caused by a communication line as the degree of balancing of the communication line is lowered.
SOLUTION: The communication device 10 establishes communication by using a power line 1 including conductive wires 1a and 1b. The communication device 10 detects the degree of balancing of the conductive wires 1a and 1b of the power line 1 by a balancing detection circuit 20 before starting communication or when it is out of communication. A controller in a digital processing circuit 15 judges whether there is a frequency band whose degree of balancing is less than a predetermined reference value or not. If there is such a frequency band, it stores it as an abnormal band. The controller controls communication so that the level of transmission signals in the abnormal band may be lower than that in other frequency bands when the communication device 10 establishes communication.
