PCT No. PCT/DE94/00433 Sec. 371 Date Sep. 25, 1995 Sec. 102(e) Date Sep. 25, 1995 PCT Filed Apr. 20, 1994 PCT Pub. No. WO94/27284 PCT Pub. Date Nov. 24, 1994Method of preparing data, in particular voice signal parameters for transmission at a low bit rate, identical signal parameters are combined interval by interval in quantized form; for further bit reduction, bits are suppressed from the total number of bits of at least two intervals, the bit difference to be suppressed being formed on the basis of the total number of unreduced bits with respect to the next-higher power of two; and the procedure supplies a better voice quality than in the case of changing the number of quantization stages by multiples of 2. |
