A method of data reduction applicable to sampled continuous signals, for example, sampled speech signals, is described and tested by computer simulation, Nonuniform sampling obtained through skipping of samples is used. The reconstruction network is a time-variable digital filter. A minimisation procedure for coefficient derivation is described.
