<p><b>Abstract</b>—A common method of constructing t-error correcting/all unidirectional error detecting (<it>t-EC</it>/AUED) codes is to choose a <it>t-EC</it> code and then to append a tail such that the new code can detect all unidirectional errors. The tail is a function of the weight of the codeword. We present a technique to reduce the weight distribution of the <it>t-EC</it> code so that the tail needed will be shorter in some cases. The weight distribution span of the code is reduced by eliminating the all-zero codeword and replacing it with a codeword of weight greater than 2<it>t</it> + 1.</p>
