Programmable multi-channel white noise generator

The pseudo-random data are widely applied in digital signal processing. White noise data is the basis of generating random data,which has the expected probability distribution. The design philosophy of a programmable digital multi-channel white noise generator is proposed in this paper. By using high speed static RAM and digital signal processing chip, In stead of the conventional shift register, the multi-channel independent white noise can be generated. The system simulation on a computer shows that the statistical characteristic of white noise data generated by this method is excellent and stable. It satisfies the requirements in the field of radar, sonar and communication. The analysis of design principle, block diagram and results of system simulation are illustrated.
