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 LA DISPOSICION DE UN DISPOSITIVO DE ESCALAMIENTO ENTRE LOS DOS CIRCUITOS EN SERIE PARA ESCALAR AL MENOS UNA SEÑAL DEL CIRCUITO EN SERIE, MAS AUN, ES POSIBLE TAMBIEN ESCALAR LA SEÑAL DE CALIDAD COMO UNA FUNCION DE DICHO DISPOSITIVO DE ESCALAMIENTO, Y LA CORRELACION POBRE PUEDE SER MEJORADA AUN MAS 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 UN CIERTO VALOR, PREFERIBLEMENTE COMO UNA FUNCION DE UNA SEÑAL DEL CIRCUITO EN SERIE.
