This paper deals with multiwavelets which are a recent
generalization of wavelets in the context of multirate filter banks
and with their applications to signal processing and especially
compression. By their inherent structure, multiwavelets are fit for
processing multi-channel signals. First, we will recall some general
results on multiwavelets and their implementations as multifilter
banks but also time-varying filter banks. Then, we will recall some
useful results on the convergence of the iterated matrix product
leading to them. Then, we will define under what conditions we can
apply systems based on multiwavelets to one-dimensional signals in a
simple way. That means we will give some natural and simple conditions
that should help in the design of new multiwavelets for signal
processing. Finally, we will provide some tools in order to construct
multiwavelets with the required properties, the so-called `balanced
