Abstract:
1. A method of classifying bit errors in run length limited data transmitted over a channel, comprising: encoding a test pattern using a run length limited line encoding to produce an encoded block of data, the encoded block of data having no more than a maximum number of consecutive bits having the same value, the encoded block of data having a run of the maximum number of consecutive bits having the same value; sending, to a receiver, the encoded block of data via the channel, the channel coupled to said receiver; receiving, using said receiver, a received block of data corresponding to the sent encoded block of data; comparing a plurality of bits in the received block of data that are subsequent to the run to an expected plurality of bits; and, classifying a type of bit error based on a mismatch between the expected plurality of bits and the plurality of bits that are subsequent to the run in the received block of data.
