Transmission arrangement for digital signals

A digital transmission arrangement operating with coded scanning samples and having a transfer function which can be changed without interrupting operation and with low interference, starting from an initial transfer function and ending with a final transfer function, with each transfer function being defined by respective coefficients, said arrangement comprising:

• a transmission means having a transfer function which is determined by transmission coefficients supplied to said transmission means;
• and switching means connected to said transmission means and switchable for selectively supplying to said transmission means a first set of coefficients (c.sub.-) constituting a set of starting coefficients and a second set of coefficients (c.sub.+) constituting a set of final coefficients, wherein said switching means comprise:
• means for supplying to said transmission means, during a selected time, a single set of intermediate coefficients (c.sub.0) between the set of starting coefficients (c.sub.-) and the set of final coefficients (c.sub.+);
• and coefficient value determining means coupled to said supplying means, for calculating and giving to said supplying means the set of intermediate coefficients (c.sub.0) values, said determining means comprising means for calculating the set of intermediate coefficients (c.sub.0) as a function of the set of starting coefficients (c.sub.-) and the set of final coefficients (c.sub.+) so that the interference to be expected during switching from the set of starting coefficients to the set of final coefficients is minimized.
