Abstract

PURPOSE:To ensure compressing transmission and expanding reception for a digital signal having a reduced error of the predicted value of a predicted signal, by carrying out a bit shift when the predicted signal exceeds the level set previously. CONSTITUTION:An analog signal supplied through an input terminal 1 receives sampling period T through an A/D converter 2 and is quantized to be supplied to a shift register part 4 that functions as a bit selecting circuit in a signal predicting circuit 3. The part 4 has shift action in a prescribed direction by the output of a comparator 10 or 17 when the predicted signal exceeds the range of set reference level which is between the upper and lower limit reference 1 levels set previously. Then transmission is carried out to the receiving system with a bit compression.
