| Métodos de pruebas objetivas para los sistemas de comunicación vocal con señales de prueba complejas |
 |
Esta Recomendación UIT-T describe métodos y procedimientos de evaluación de terminales complejos, componentes de red y sistemas de transmisión. Los métodos de prueba utilizan principalmente las señales descritas en las Recomendaciones UIT-T P.50, P.59 y P.501. Se describen las posibles repercusiones sobre la percepción subjetiva de la calidad de la voz, para diversas implementaciones técnicas y en distintas situaciones, explicándose los procedimientos de medida pertinentes. |
