Foe executing the code excitation linear prediction (CELP) coding, for example, .alpha.-parameters are taken out from the input speech signal by a linear prediction coding (LPC) analysis circuit 12. The .alpha.-parameters are then converted by an .alpha.- parameter to LSP converting circuit 13 into linear spectral pair (LSP) parameters and a vector of these line spectral pair (LSP) parameters is vector-quantized by a quantizer 14. The changeover switch 16 is controlled depending upon the pitch value detected by a pitch detection circuit 22 for selecting and using one of the codebook 15M for male voice and the codebook 15F for female voice for improving quantization characteristics without increasing the transmission bit rate.

La présente invention concerne un dispositif de branchement pour signaux haute fréquence, dans lequel le nombre de bornes de connexion (B25) peut être augmenté. Le dispositif de branchement pour signaux haute fréquence comprend un corps principal (A) équipé de bornes d'entrée et de sortie (A3 et A4) servant à brancher les câbles principaux, et un corps de branchement (B) qui comprend une borne de branchement (B25) destinée au branchement d'un câble de dérivation. On peut augmenter le nombre de bornes de branchement en remplaçant le corps de branchement sans modifier le corps principal. Un circuit de branchement (B15) servant à brancher le signal haute fréquence provenant du câble principal est prévu sur le corps de branchement. Par conséquent, on peut remplacer aussi le circuit de branchement en remplaçant le corps de branchement.
