Abstract: Digital transmission arrangement operating with coded scanning samples and whose transfer function can be changed without interrupting operation and with low interference starting from an initial transfer function to a final transfer function, the arrangement including a switching device for the transmission coefficients to be associated with each transmission member of the transmission arrangement for switching from a set of starting coefficients to a set of final coefficients, the switching device being configured to switch in a single set of intermediate coefficients (c.sub.0) between the set of starting coefficients (c-) and the set of final coefficients (c+), and the set of intermediate coefficients (c.sub.0) being determined, as a function of the set of starting coefficients (c-) and the set of final coefficients (c+), so that he interference to be expected during switching is minimized.
