Abstract A new Gauss noise generating method is proposed, which is based on Lindeberg-Levy theorem. In order to verify this method, computer simulation was carried out. Simulation results indicate that the principle of the method is correct and it performs well for all kinds of noise generating systems that are based on DSP or FPGA.
