Query: On a question of Babadi and Tarokh   In a recent remarkable paper, Babadi and Tarokh proved the "randomness" of
sequences arising from binary linear block codes in the sense of spectral
distribution, provided that their dual distances are sufficiently large.
However, numerical experiments conducted by the authors revealed that Gold
sequences which have dual distance 5 also satisfy such randomness property.
Hence the interesting question was raised as to whether or not the stringent
requirement of large dual distances can be relaxed in the theorem in order to
explain the randomness of Gold sequences. This paper improves their result on
several fronts and provides an affirmative answer to this question.
