Noise Generator with DSP96002

Abstract

When measuring the transfer and properties of many electronic circuits it is necessary to use a measuring signal with noise of defined properties. In the paper, the design and software implementation are described of a generator of pseudorandom binary noise signal of adjustable length and with repetition of pseudorandom binary signal sequence. The parameters of noise outputs are stable, well defined and variable over a wide range. The noise generator described in this paper is a very simplified and software-emulated version of the HP 722A noise generator produced by Hewlett-Packard (1971).
