We give explicit evaluations of Walsh transforms of Gold type functions (Formula presented) when gcd (b(− a, k)=gcd(b + a, k) and Kasami-Welch type functions (Formula presented),when t is odd, gcd (2k − 1, 2a +1) =1,k is even. Therefore we correct a recent result of Roy’2012, we solve an open problem stated in Roy’2012 and we improve and generalize some results of Roy’2012 and Lahtonen-McGuire-Ward’2007.
