Abstract
A computer programmed to process a method for generating a sequence of random numbers of a 1/f noise has the following steps: 1). Determining a constant step &dgr; or instants of consideration t to t ; 2). Determining a desired spectral value &bgr;; 3). Determining the number n of the random numbers, to be generated, of a 1/f noise; 4). Determining an intensity constant const; 5). forming a covariance matrix of dimension (n×n); and 6). Forming the Cholesky decomposition of the covariance matrix , with the following steps being carried out for each sequence, to be generated, of random numbers of a 1/f noise: 1). Forming a vector of length n from random numbers normally distributed in [0,1], and 2). Generating a vector of length n of the desired 1/f-distributed random numbers by multiplying the Cholesky-decomposition by the vector .
