Abstract£ºThe notion of balancing is introduced to M-band biorthogonal multiwavelet system£¬the corresponding balanced conditions are presented£¬and some equivalent propositions of balanced multiscale functions are established£®Based on these propositions£¬algorithms for constructing balanced multiscale function and multiwavelets are proposed£®If discrete polynomial signals are dealt with by the algorithm£¬the signals are preserved by the lowpass filter and canceled by the highpass filter£¬and the algorithm keeps symmetry of biorthogonal multiwavelet system£®The numerical examples show the applied significance in signal processing£®
