Correction to "A note on the Shannon capacity of runlength-limited codes"
J. Ashley, M. Hilden, P.N. Perry, Paul H. Siegel · IEEE Transactions on Information Theory · 1993
Two remarks in the above-titled paper by J. Ashley and P.H. Siegel (see ibid. vol.33, no.4, p.601-5, July 1987) pertaining to the rationality of the base b capacity of (d, k) runlength-limited (RLL) constraints and (d, k; c) charge-constrained RLL constraints, where b>2, are corrected.>
