Abstract

Operation and effectiveness of most electronic systems is strongly affected by their noise rejection capability. The performance they exhibit in the presence of noise is therefore assessed since the early production stage, as well as routinely during periodical maintenance actions. To carry out appropriate tests suitable noise sources are needed. Actually, only white noise sources are widely available on the market; generators capable of producing colored noise are instead very unusual. In theory, ordinary arbitrary waveform generators could be used, once suitably programmed to serve as noise sources. But, test and measurement technicians charged barely find application notes that support them in taking this step. The paper gives relevant remarks concerning the simulation of colored noise, and proposes an analog generator that exploits an arbitrary waveform generator as noise source. The proposed generator is capable of producing noise signals characterized by structured spectral patterns.
