摘要： A small and inexpensive signal detector is provided, which can be simply used for noise detection as a development tool for development engineers of systems and devices. A signal suppression filter (22) of inhibiting high-frequency signals contained in power voltage and a signal separation filter (23) of inhibiting transmission of the high-frequency signals are provided in series in power lines (21A), (21B) connected to a power input terminal (T1), and high-frequency signals contained in power voltage between a power output terminal (T2) and the signal separation filter (23) are outputted from signal output terminals (T3) to (T5). High-frequency signals from a power source can be blocked by the signal suppression filter (22) and the signal separation filter (23), so that influence of power noise on a measurement system can be eliminated. Since the signal separation filter (23) situated between the signal suppression filter (22) and the power output terminal (T2) inhibits high-frequency signals generated in a device to be measured (3) from being absorbed by the signal suppression filter (22), a signal detection level can be prevented from being reduced at the signal output terminals (T3) to (T5).

摘要： In a power line noise filter, a detection circuit detecting variations in electric current in two conductive lines of an electric power line, thereby detecting common mode noise that causes a change in electric current in the power line. A phase-inverted signal generation circuit then generates a phase-inverted signal whose is inverted to that of the noise detected by the detection circuit. Further, an injection circuit causes a change in electric current corresponding to the phase-inverted signal, for the two conductive lines of the electric power line. The common mode noise causing a change in electric current in the electric power lines is thereby canceled.

摘要： A noise suppressor capable of obtaining a favorable attenuation characteristic even in the case where a plurality of inductors on a conductive wire are magnetically coupled to each other. The noise suppressor includes a first inductor and a second inductor which are magnetically coupled to each other on a first conductive wire, a third inductor having one end connected to the other end of a first capacitor and the other end of a second capacitor and the other end connected to ground, and a fourth inductor and a fifth inductor which are magnetically coupled to each other on a second conductive wire. While it is considered that the coupling coefficients k1 through k6 between the inductors are smaller than 1 in reality, in particular, on the basis of the condition that the coupling coefficients K1 through k6 are smaller than 1, the inductance of the third inductor is set to a value corresponding to the actual values of the coupling coefficients k1 through k6 so as to obtain a desired noise attenuation characteristic.
