Abstract

UN CIRCUITO DE SINCRONIZACION DE FASE INCLUYE UN CONVERTIDOR DIGITO/ANALOGICO (60, 61, 62, 63) DEL TIPO MULTIPLICADOR DE VELOCIDAD DE BITS. LA PALABRA DE ENTRADA AL CONVERTIDOR (PHER) ES ACTUALIZADA AL MISMO TIEMPO QUE CADA PERIODO HORIZONTAL (H) DE UNA SEÑAL DE TELEVISION. LA INFORMACION DE FASE DE UNA SEÑAL DE SALIDA (BRM) DEL MULTIPLICADOR DE VELOCIDAD DE BITS QUE SE OBTIENE EN UN PERIODO HORIZONTAL (H) ES RETENIDA PARA AFECTAR A LA FASE EN EL PERIODO HORIZONTAL INMEDIATAMENTE SIGUIENTE.
