So, here the
LPC operations involve in the modelling the vocal track. The excitation
is given in the form of the impulse train or the random noise. The coefficients
of this filter, which is a vocal track filter, are obtained in time domain
using linear prediction techniques and only selected parameters are chosen,
quantized and sent onto the line. The error signal is excitation to the decoder and the receiver and the received information about the error signal at the receiver is used to determine the appropriate excitation synthesis filter. | ![]() |
