Abstract

APARATO PARA MULTIPLICAR UNA SEÑAL DE DATOS DE MUESTRA POR UNA SINUSOIDE QUE TIENE UN PERIODO EL CUAL ES UN MULTIPLO DE LA VELOCIDAD DE LA MUESTRA, INCLUYE UNA PLURALIDAD DE MEDIOS DE ESCALADO DE MUESTRA (116) PARA ESCALAR LA SEÑAL DE DATO DE MUESTRA POR FACTORES CORRESPONDIENTES AL SENO DE UN ANGULO SOBRE UN RANGO ANGULAR DE 90 GRADOS EN INCREMENTOS ANGULARES DE 2 VECES EL NUMERO PI DIVIDIDO POR DICHO MULTIPLO. UN MULTIPLEXOR (118,120) MULTIPLICA LAS MUESTRAS ESCALADAS A LA VELOCIDAD DE LA MUESTRA PARA PRODUCIR UNA SEÑAL CORRESPONDIENTE A LA SEÑAL DE DATO DE MUESTRA MULTIPLICADA POR LA SINUSOIDE. LA VELOCIDAD DE LA MUESTRA ESTA CERRADA EN FASE A LA SINUSOIDE. SE DESCRIBE UNA REALIZACION PARA DEMODULAR LA SEÑAL DE DIFERENCIA ESTEREO DE UNA SEÑAL DE SONIDO BTSC CON UN CIRCUITO DE PROCESAMIENTO DIGITAL DE BIT EN SERIE.
