Suppression of overflow limit cycles in LDI allpass/lattice filters
Lennart Harnefors, J. Holmberg, S. Signell · 2003
In this paper, it is shown that overflow limit cycles can be suppressed in a class of lossless digital integrator allpass filters. This holds for any filter order, provided that saturation overflow characteristics are used at the input of each delay, and for certain restrictions, as of the multiplier values.
