Abstract
Transfer and pulse-response characteristics of Walsh filters are found to insure detecting (for four noise immunity levels) the distortion syndrome of a short sliding sample containing the typical fragment of the delta-modulated measuring pulse envelope in order to decode the sample by a one-step threshold procedure. The proposed algorithm of distortion correction with adapting to noise intensity possesses linear computation complexity and is adequate to the architecture of modern digital signal processors.
