Abstract

UN GENERADOR DE SEÑAL DE RELOJ INCLUYE UN OSCILADOR DE CUARZO (1) QUE GENERA SEÑALES DE RELOJ QUE PASAN A TRAVES DE UN FILTRO DE PASO BANDA (2) QUE FORMA SEÑALES DE RELOJ DE REFERENCIA SINUSOIDALES. LAS SEÑALES DE RELOJ SE ALIMENTAN A UN MULTIPLICADOR (3) Y SE RETARDAN EN UN CUARTO DE PERIODO MEDIANTE UNA UNIDAD DE RETARDO DE UN CUARTO DE PERIODO (4), PARA FORMAR SEÑALES DE RELOJ COS (FCT) QUE SE APLICAN DESPUES A UN MULTIPLICADOR (5). CUANDO SE INTRODUCE UNA SEÑAL SINCRONIZADA HORIZONTAL DESDE UNA FUENTE EXTERNA, UN CONVERTIDOR DE CORRIENTE CONTINUA/ALTERNA (6) TOMA MUESTRAS DE LA SEÑAL DE RELOJ DE REFERENCIA CON LA SEÑAL DE SINCRONIZACION HORIZONTAL Y TRANSMITE UNA SEÑAL DIGITAL A UNA UNIDAD DE OPERACION (7), QUE PRACTICA UNA DIFERENCIA DE FASE ENTRE UNA FASE ABSOLUTA DE LA SEÑAL DIGITAL Y UNA FASE PREDETERMINADA, Y GENERA COMPONENTES DE ONDA SINUSOIDAL EN (A-B) Y UN COMPONENTE DE ONDA DE COSENO COSENO (A-B) CORRESPONDIENTE A LA DIFERENCIA DE FASE. EN EL MULTIPLICADOR SE MULTIPLICA LA SEÑAL DE RELOJ DE REFERENCIA SEN (FPT) POR EL COMPONENTE DE ONDA SINUSOIDAL SEN (A-B), Y EN EL MULTIPLICADOR (S) SE MULTIPLICA LA SEÑAL DE RELOJ DE COSENO COS (FCT) POR EL COMPONENTE DE ONDA DE COSENO COS (AB). LOS RESULTADOS DE LA MULTIPLICACION SE SUMAN EN UN SUMADOR (9) Y LA SUMA SE CONVIERTE EN UN VALOR BINARIO MEDIANTE UN COMPARADOR (12) QUE GENERA UN IMPULSO DE RELOJ DE SALIDA W.CK.
