<p>A signal coding apparatus includes a signal dividing section (110, 150) for dividing an input signal in units of frames and in units of bands, a pulse allocating section (200, 210, 215, 310, 320, 330, 650, 651, 710, 810, 900, 910, 1010, 1120, 1150) for determining a performance request value for each of the bands, for determining a number of pulses for each of the bands from the performance request value for the band, and for adaptively allocating the determined numbers of pulses to the bands for every frame, and a plurality of coding circuits (400, 600, 700, 800, 1000, 1100) respectively provided for the bands, wherein each of said plurality of coding circuits generates a transmission signal for a corresponding band for every frame based on the number of pulses allocated to the corresponding band. <IMAGE></p> |
