ABSTRACT:
A waveform encoding and decoding apparatus is disclosed which comprises a memory, a coding device, a packing unit, and a storage device. The coding device encodes an analog waveform into digital coded data having digital coded data words each having a predetermined length. The packing device "packs" groups of more than one of the coded data words into packed data words each having a predetermined length. The storage device stores the packed data words into respective segments located in the memory. The segments which are located in the memory each have a bit length equal to the predetermined length of the packed data words. A data transfer device may also be provided for transferring and rearranging data between segments located in the memory.
