Abstract:
1. A noise analysis program for unwanted radiation noises of an electronic equipment which can transmit and receive electro-magnetic waves via an antenna, comprising: a first step for extracting a source of unwanted radiation noise which is generated from a circuit board mounted on the electronic equipment; a second step for acquiring noise characteristics of the unwanted radiation noise which is emitted by the extracted noise source; a third step for acquiring an attenuation ratio of the unwanted radiation noise which is emitted by the noise source and propagated to a feed point of the antenna; a fourth step for calculating a correlation value between the noise characteristics and the attenuation ratio of the unwanted radiation noise; and a fifth step unit for identifying, based on a comparative result between the calculated correlation value and the predetermined allowable value, a disincentive source which may cause the electronic equipment to malfunction due to interference of the unwanted radiation noise into the circuit board via the antenna.
