Abstract [eng] Mathematical model for UD (Up and Down) procedure of digital signal processing was formulated as a simple homogeneous Markov chain. For such Markov chains were investigated transition probability distributions by step numbers sufficient for practically stationary process. Conditions were analysed under which infinite Markov chain may be replaced by a finite Markov chain practically equivalent to the infinite chain, i.e. difference between variances of both processes is negligible. It was shown how these variances depend on UD procedure step length and step number parity.
