Abstract

PARA GRABAR PALABRAS DE INFORMACION DE N-BIT EN UN MEDIO DE GRABACION (101), UNA PALABRA DIGITAL DE 1-BIT SE UNE A DICHA PALABRA DE INFORMACION. LAS PALABRAS DE INFORMACION DE (N+1)-BIT SON CODIFICADAS EN UN PREGRABADOR AT (10) EN PALABRAS DE CANAL DE (N+1)-BIT (CW) QUE SON GRABADAS EN EL MEDIO DE GRABACION. CADA VEZ QUE SE UNEN PALABRAS DIGITALES DE 1-BIT SE PRODUCE QUE EL VALOR SUMA DIGITAL RESULTANTE EN LA SEÑAL DE SALIDA DEL PREGRABADO MUESTRE UNA CONDUCTA DESEADA EN FUNCION DEL TIEMPO. POR EJEMPLO, UNA SEÑAL PILOTO PUEDE SER INSERTADA EN LA CORRIENTE DE DATOS DE PALABRAS CANAL, DICHA SEÑAL PILOTO PUEDE SER UTILIZADA PARA EFECTUAR UN TRACEADO DURANTE LA REPRODUCCION. PARA N, UNO DE LOS NUMEROS SIGUIENTES VERIFICA: A (MAYOR O IGUAL) 2 Y N (MAYOR O IGUAL) 1. PREFERENTEMENTE N >> M, POR EJEMPLO N (MAYOR O IGUAL) 10.
