On the basis of the theory of the causal Markov processes with discrete arguments, the mathematical model and algorithm of non-linear filtering the multidigit halftone images (MDHI) transferred by multiposition FM pulse signals are synthesized. Such transition is caused by approximation of MDHI by Markov chain with number of states more than two that allows us to reduce transmission time of MDHI several times. Thus losses of noise stability at the transmission of MDHI increase the same times. The synthesized algorithm allows one to offset these losses due to implementation not only spatial but also interbit statistical redundancy of MDHI.
