Summary: In this paper we study the distribution of the infinite word $t_{q,n} := (s_{q}(k)$ mod $n)_{k=0}^{\infty }$, which we call the generalized Thue-Morse sequence. Here $s_{q}(k)$ is the digit sum of $k$ in base $q$. We give an explicit formulation of the exact minimal value of $M$ such that every $M$ consecutive terms in $t_{q,n}$ cover the residue system of $n$, i.e., ${0, 1, \dots , n-1}$. Also, we prove some stronger related results.
