RADIATION NOISE GENERATING METHOD AND RADIATION NOISE GENERATOR

摘要

PURPOSE: To make it possible to generate radiation noise which is equivalent to radiation noise generating from current flowing in lead wires located at various locations by selectively flowing current generating radiation noise in plural lead wires. ;CONSTITUTION: A program power source 1 is connected with a low frequency oscillator 2, the output is superposed on power supply voltage, a simulation signal generating simulation noise is generated and it is supplied to a radiation noise generator 3. The generator 3 is composed of lead wires L1 to L9 and switches SW1 to SW9 provided on each lead wire, a simulation signal flows in the lead wire corresponding to the switch which is turned on and simulation noise is radiated from the wire. A load resistance 4 is connected with the radiation noise generator 3 and simulation noise generates in the same way as an actual electrical equipment. Therefore, by the states of the switches SW1 to SW9, the simulation signals flowing in the lead wires L1 to L9 can be controlled and simulation noise in various conditions can be generated.;COPYRIGHT: (C)1994,JPO&Japio
