Abstract :
Noise sources are needed for test and validation of noise sensitive electronic systems but only wide band white noise sources are directly available on the market. In this paper a programmable colored noise generator is proposed. The system allows to configure the spectral features of the noise and is implemented with a Field Programmable Gate Array that produces the digital samples of the noise and a Digital to Analog Converter that produces the analogue output. The proposed generator overcomes the state of the art in terms of bandwidth and flexibility and produces a noise sequence whose length is unlimited for practical purposes. Experimental results show that the bandwidth of the generated noise can be selected up to a maximum of 120 MHz while defining the power spectral density with a frequency resolution equal to 0.2 % of the selected bandwidth.
