Abstract: To any pair of diadic intervals $ [I,\omega ]$ with / Q $ I \subseteq [0,1]$ and $ \omega = [{N_\omega },{N_\omega } + \vert I{\vert^{ - 1}})$ we associate the function $ {u_{[I,\omega ]}}(x) = \vert I{\vert^{ - 1/2}}{e^{i{N_w}x}}{\chi _I}(x)$. In this paper we will give a condition under which a collection $ B$ of such pairs satisfies the inequality $ B$ for any $ ab$ in $ f$.
