<p>A predictive coding device has an input terminal through which a sampled value (xi) is input, a predicting circuit for outputting a predicted value (x/< ANd >)i for the sampled value which has been input through the input terminal, and a look-up table (12) arranged to receive, as a readout address, the sampled value (xi) input through the input terminal and the predicted value (x/< ANd >i) and then to output a predictive coded value (xi). On the basis of the input sampled value (xi) and the predicted value (x/< ANd >i), the predictive coding device determines the readout address for the look-up table (12) which stores a table providing the predictive coded value.</p> |
