FIELD: information technology.
SUBSTANCE: device for quantisation of a signal in accordance with the embodiment is configured for quantisation of a smoothed input value (such as a vector of frequency of spectral lines) to generate a corresponding output value, where the smoothed value is based on a scaling factor and quantisation error of the previous output value.
EFFECT: high quality voice encoding using time quantisation with limitation of the noise of parametres of the spectral carrier.
