METHOD OF AND APPARATUS FOR RECOVERING DIGITAL INFORMATION IN A RUN LENGTH LIMITED CODE |
摘要 |
Run length limited codes, such as (1,7) codes are recovered with a dual channel recovery system in which the high resolution channel normally supplies the output (recovered) signal. The low resolution channel includes a detector, such as a delay device and gate, to detect a predetermined absence of transitions in the low resolution signal (which is indicative of long strings of successive zeros) to inhibit the high resolution channel from supplying the output. The result is to effectively block the high resolution channel from providing a false output. |
