Abstract
SE PRESENTA UN RECEPTOR QUE TIENE UNA LINEA DE SEÑAL QUE INCORPORA UN SINTONIZADOR, UN CIRCUITO DEMODULADOR PARA SUMINISTRAR UNA SEÑAL ESTEREO MULTIPLE QUE COMPRENDE UNA SEÑAL DE SUMA ESTEREO DE LA BANDA DE BASE (L+R), UNA SEÑAL AUXILIAR ESTEREO DE 19 KHZ Y UNA SEÑAL DE DIFERENCIA ESTEREO (L-R) QUE ES EL DOBLE DE LA AMPLITUD DE LA BANDA LATERAL MODULADA SOBRE UNA SUBPORTADORA SUPRIMIDA DE 38 KHZ, UN CONMUTADOR ELECTRONICO PARA CONVERTIR UNA SEÑAL ANALOGICA EN UNA SEÑAL DE TIEMPO DISCRETO Y UN DECODIFICADOR ESTEREO PARA LA DECODIFICACION MULTIPLE DE DIVISION DE TIEMPO DE UNA SEÑAL MULTIPLE ESTEREO DE TIEMPO DISCRETO EN UNA SEÑAL ESTEREO IZQUIERDA DE TIEMPO DISCRETO Y UNA SEÑAL ESTEREO DERECHA DE TIEMPO DISCRETO. PARA REALIZAR UNA SELECCION EFECTIVA DE LA SEÑAL MULTIPLE ESTEREO POR MEDIO DE UN FILTRO DE PASO BAJO FACILMENTE INTEGRABLE, EL DECODIFICADOR ESTEREO COMPRENDE UN CIRCUITO FILTRADOR DE PASO BAJO DE MEDIA BANDA DE TIEMPO DISCRETO QUE TIENE UNA RESPUESTA DE IMPULSO FINITA, CON UNA BANDA DE TRANSICION QUE SE ENCUENTRA SUBSTANCIALMENTE SITUADA EN EL RANGO DE DICHA SEÑAL MODULADA DE DIFERENCIA ESTEREO Y CON UNA TRANSFERENCIA DE VALOR QUE SE SITUA EN LA FRECUENCIA DE DICHA SUBPORTADORA ESTEREO DE 38 KHZ, DICHO CIRCUITO FILTRADOR TIENE UNAS CARACTERISTICAS DE TRANSFERENCIA DE AMPLITUD SUBSTANCIALMENTE LINEALES ASI COMO UNA CARACTERISTICAS DE TRANSFERENCIA DE FASE EN LA BANDA DE TRANSICION, DICHO RECEPTOR TAMBIEN INCLUYE UN CIRCUITO DE INTERPOLACION QUE ESTA ACOPLADO CON LA SALIDA DEL CIRCUITO FILTRADOR PARA EFECTUAR UNA CONVERSION SECUENCIAL DE TIEMPO DE LOS VALORES DE MUESTRO SOBRANTES DE LA SEÑAL DE SALIDA DEL CIRCUITO FILTRADOR EN PARES SECUENCIALES DE TIEMPO DE VALORES DE MUESTREO QUE SE PRODUJERON SIMULTANEAMENTE, Y UN CIRCUITO DESMATRIZADOR ACOPLADO AL CIRCUITO DE INTERPOLACION PARA LA COMBINACION LINEAL DE DICHOS PARES DE VALORES DE MUESTREO Y PARA LA COMPENSACION DE LOS ACOPLAMIENTOS ENTRE LAS SEÑALES ESTEREO IZQUIERDA Y DERECHA PROVOCADOS POR EL CIRCUITO FILTRADOR.
