PURPOSE:To obtain the irregular wave signal featuring the specified spectrum by making the white noise signal pass through the device featuring the specified frequency response properties. CONSTITUTION:The white noise signals which are being shifted with every unit time within white noise signal generator 11 are drawn out in parallel via lines 11-0, 11-1-11-n, and these signals means XWH(t-nDELTAt) in Eq. (I). Then the multiplication is given between these signals and coefficients a0, a1-an which are obtained from Eq. (II), where Hg(omega) whows the frequency response number of irregular wave signal generator 1, and then stored in memory means 12 through multiplication means 13. These multiplication value are given to addition means 14 via lines 13-00, 13-10-13-n0. Then the increase/drcrease staircase type signals generated from means 14 are filtered 15 to obtain the desired irregular wave signals. |
