Abstract

SE PROPORCIONA UN DISPOSITIVO PARA DETERMINAR LA CALIDAD DE UNA SEÑAL DE SALIDA QUE VA A SER GENERADA POR UN CIRCUITO DE PROCESADO DE SEÑAL CON RESPECTO A UNA SEÑAL DE REFERENCIA, CON UN PRIMER CIRCUITO EN SERIE PARA RECIBIR LA SEÑAL DE SALIDA Y CON UN SEGUNDO CIRCUITO EN SERIE PARA RECIBIR LA SEÑAL DE REFERENCIA, Y QUE GENERA UNA SEÑAL DE CALIDAD OBJETIVA POR MEDIO DE UN CIRCUITO DE COMBINACION ACOPLADO A LOS DOS CIRCUITOS EN SERIE. LA POBRE CORRELACION ENTRE DICHA SEÑAL DE CALIDAD OBJETIVA Y UNA SEÑAL DE CALIDAD SUBJETIVA VALORADA POR OBSERVADORES HUMANOS PUEDE SER MEJORADA CONSIDERABLEMENTE MEDIANTE REDUCCION, EN UN DISPOSITIVO DIFERENCIAL, PRESENTE EN EL CIRCUITO DE COMBINACION, PARA DETERMINAR LA DIFERENCIA ENTRE LAS DOS SEÑALES DE LOS CIRCUITOS EN SERIE, DICHA DIFERENCIA POR CIERTO VALOR, PREFERIBLEMENTE COMO UNA FUNCION DE UNA SEÑAL DE LOS CIRCUITOS EN SERIE, LA CORRELACION POBRE PUEDE SER MEJORADA MAS DISPONIENDO UN CIRCUITO DE ESCALAMIENTO ENTRE LOS DOS CIRCUITOS EN SERIE PARA ESCALAMIENTO DE AL MENOS UNA SEÑAL DEL CIRCUITO EN SERIE, AUN MAS, ES POSIBLE TAMBIEN ESCALAR LA SEÑAL DE CALIDAD COMO UNA FUNCION DE DICHO DISPOSITIVO DE ESCALAMIENTO.
