Chaotic signals generated by digital filter overflow

The paper surveys the chaotic behaviour of digital filter overflow oscillations. The behaviour patterns of 1st, 2nd and 3rd order filters are described and the available stochastic characteristics of oscillations with chaotic features are illustrated by means of probability density functions and power density spectra for a range of filter parameters and initial states. The analysis and simulation results provide a basis for the design of digital systems which generate signals with a variety of prescribed characteristics. Typical examples are included.<<ETX>>
