Abstract
LOS COMPONENTES DE FRECUENCIA SE CALCULAN DESDE LA SEÑAL DE VOZ FILTRADA POR STP. LAS AMPLITUDES DE ESTOS ESTAN COMBINADOS DE UNA MANERA TAL QUE LOS VALORES RESULTANTES ESTAN ASOCIADOS A FRECUENCIAS QUE ESTAN COLOCADAS DE MANERA EQUIDISTANTE EN UNA ESCALA DE BARK LINEAL. DICHOS COMPONENTES SE CUANTIFICAN, POSIBLEMENTE DESPUES DEL ESCALADO. EN EL DESCODIFICADOR, LOS COMPONENTES SE VUELVEN A DISTRIBUIR SOBRE EL ESPECTRO DE FRECUENCIA. EN EL CODIFICADOR, LA REGULARIDAD FUNDAMENTAL D SE DETERMINA CON UN METODO LTP, DESPUES DE LO CUAL SE TRANSMITE. EN EL DESCODIFICADOR SE DETERMINAN LAS FASES DE LA SEÑAL RECONSTRUIDA EN LA SEPARACION D EN EL PASADO. ESTAS FASES SE COMBINAN CON LAS AMPLITUDES YA PRESENTES EN EL ESPECTRO DE FRECUENCIA, DESPUES DE LO CUAL TIENE LUGAR LA TRANSFORMACION OTRA VEZ AL DOMINIO DE TIEMPO. ENTONCES SE LLEVA A CABO EL FILTRADO STP INVERSO.
