In a speech coder, an excitation quantizer 360 retrieves the positions of M non-zero amplitude pulses, which together constitute an excitation, by using spectral parameters and with a different gain for each group of the pulses less in number than M.

Dans un codeur de paroles, un quantificateur d'excition 360 retrouve les positions de M impulsions d'amplitude non nulle constituant une excitation en utilisant des paramètres spectraux, ainsi qu'un gain différent pour chaque groupe de moins de M impulsions.
