Abstract

EN UN APARATO REPRODUCTOR DE VELOCIDAD VARIABLE PARA SEÑALES DIGITALES DE VIDEO DONDE LA VELOCIDAD DE DESPLAZAMIENTO DE LA CINTA PUEDE SER CONTROLADA CON UN ALTO GRADO DE PRECISION, UNA UNIDAD DE PROCESAMIENTO DE FASE DE TRAZA (33) EMPLEADA EN UN MICROORDENADOR (25) CALCULA LOS NUMEROS DE PISTAS Y DE BLOQUES DE SINCRONIZACION. ESTA FASE DE TRAZA SE COMPARA CON UNA FASE DE TRAZA DE REFERENCIA (REF) EMITIDA POR UN CONTADOR CICLICO (29) PARA PRODUCIR UN ERROR DE FASE QUE ES SUMINISTRADO A UNA UNIDAD DE CONTROL DE VELOCIDAD (26).
