Abstract
The present invention relates to a method and system for providing an analog Gaussian noise signal having the predetermined probability distribution function, bandwidth and center frequency. A band-limited digital noise signal indicative of a Gaussian noise signal having a predetermined Gaussian probability distribution function is ΣΔ modulated generating a pulse-density modulated 1-bit sequence representing a Gaussian noise signal having a predetermined probability distribution function, bandwidth and center frequency. Using an analog low-pass filter the pulse-density modulated 1-bit sequence is then converted into a respective analog Gaussian noise signal having the predetermined probability distribution function, bandwidth and center frequency. The method and system are successfully employed in numerous applications such as in histogram testing and probabilistic digitization.
