Abstract
Bounds on the redundancy of Huffman codes in terms of the probability p 1 of the most likely source letter are provided. In particular, upper bounds are presented that are sharper than the bounds given recently by R.G. Gallager (ibid., vol.IT-24, no.6, p.668-74, Nov.1978) and by R.M. Capocelli et al. (ibid., vol. IT-32, no.6, p.854-857, Nov. 1986) for an interval 2/(2l+1+1)<p 1<1/(2l-1), l ⩾2. It is shown that the new bounds are the tightest possible for these intervals
