Moving algorithm implementing wavelet transform in real time surveyed. The scheme of operation of algorithm and its mathematical exposition is offered. Demands to dynamic characteristics of the measuring channel, basing on meanings of the expressions obtained for an estimation of sizes of evaluations of algorithms of moving discrete wavelet transform are defined.
