Description: In the simplest form of LPC coding, voiced excitation consists of a train of
impulses which differs a great deal real world cases, where each excitation
pulse possesses a certain shape, different an ideal impulse. The shape of the
pulse contains important information and is captured by the MELP coder through
Fourier magnitudes (next section) of the prediction error. These quantities are used
to generate the impulse response of the pulse generation filter (Figure 17.1), responsible
for the synthesis of periodic excitation.
