BURST ERROR DETECTION SYSTEM

摘要

PURPOSE:To detect exactly the generation of burst error in a short time by adding a counter and a comparator circuit in an error correcting decoder. CONSTITUTION:Counter CT is reset at every N-bound length of convolutional code and counts the number of pulses of syndrome sequence signals which are generated in the N-bound length time. A threshold number is set to comparator circuit CP previously so that the output of compatator circuit CP can be obtained when the number of outputs of counter CT has exceeded the threshold number, and as a result, the burst error in the N-bound length time can be decided immediately.
