Abstract
A method is given to generate and analyze frequency-weighted pseudo-random audio noise. The only analog elements are a digital-to-analog converter and a simple interpolating filter. The method is attractive because it easily accomodates arbitrary spectra and equalization of any known frequency dependent elements subsequent to the source. A method is given to analyze the effects of a finite word length on the output spectrum.
