Abstract
(EN)
A random value integration unit 175 calculates the product of the output of a random value generation unit 174 and the output of a diffusion width generation unit 173, thereby outputting a random value output from the random value generation unit 174 within a diffusion width Rand output from the diffusion width generation unit 173. A triangular wave signal generation unit 176 generates a triangular wave signal corresponding to a second carrier frequency fc2 obtained by adding the random value output from the random value integration unit 175 to a first carrier frequency fc1 that is the output of a carrier frequency setting unit 171. That is, the diffusion width of the first carrier frequency fc1 is widened to obtain the second carrier frequency fc2, and the second carrier frequency fc2 is used as a carrier frequency.

Selon l'invention, une unité d'intégration 175 de valeur aléatoire calcule le produit de la sortie d'une unité de génération 174 de valeur aléatoire et de la sortie d'une unité de génération 173 de largeur de diffusion, fournissant ainsi une sortie de valeur aléatoire à partir de l'unité de génération 174 de valeur aléatoire à l'intérieur d'une largeur de diffusion R et une sortie à partir de l'unité de génération 173 de largeur de diffusion. Une unité de génération de signal à onde triangulaire 176 génère un signal à onde triangulaire correspondant à une seconde fréquence porteuse fc2 obtenue en ajoutant la sortie de valeur aléatoire de l'unité d'intégration 175 de valeur aléatoire à une première fréquence porteuse fc1 qui est la sortie d'une unité de définition 171 de fréquence porteuse. C'est-à-dire que la largeur de diffusion de la première fréquence porteuse fc1 est élargie pour obtenir la seconde fréquence porteuse fc2, et la seconde fréquence porteuse fc2 sert de fréquence porteuse.

ランダム値積算部175は、ランダム値生成部174の出力と拡散幅生成部173の出力との積により、拡散幅生成部173より出力された拡散幅Rand内において、ランダム値生成部174より出力されたランダムな値を出力する。三角波信号生成部176は、キャリア周波数設定部171の出力である第1のキャリア周波数fc1にランダム値積算部175より出力されたランダムな値を足した第2のキャリア周波数fc2に応じた三角波信号を生成する。すなわち、第1のキャリア周波数fc1の拡散幅を広げて第2のキャリア周波数fc2とし、これをキャリア周波数として用いる。
