Abstract(in Japanese) (See Japanese page)
Abstract(in English) Recently,telecommunications equipments have been constructed in large system by multi-vendor.So the specification value for radiated interference in equipments is provided for an element of equipment,it is not clear that whether the specification value guarantees the value in whole equipment system.Then it is necessary to provide specification value for each element.For this purpose,it is required to be clear the superposition of radiated interference.In this paper,the relation between phase variation in the harmonics and characteristic of superposition of radiated interference is discussed.As the result,in case that the amount of phase variation is over 180 degrees,characteristic of superposition agrees well with power sum within 4dB,and it agrees with characteristics of superposition of radiated interference in PBX within 5dB.
