| The pseudo-random data are widely applied in digital signal processing and analysis. Gaussian noise is one of the most useful signal forms. Anew method of generating Gaussian noise data is proposed in this paPer. With advanced digital sigal prosessing chip, high precislon Gaussian noise data can be generated. The noise data generated by a sonar simulator using this new method are satisfactory and stable. They satisfy the requirements in the field of sonar and communication. The analysis of design principle,block diagram, and practial results are illutrated- |
