Abstract: We construct an analog of two-scale relations for basis trigonometric splines with uniform knots corresponding to a linear differential operator of order $2r+1$ with constant coefficients $ {\mathcal L}_{2r+1}(D)=D(D^2+\alpha_1^2)(D^2+\alpha_2^2)\ldots (D^2+\alpha_r^2), $ where $\alpha_1,\alpha_2,\ldots,\alpha_r$ are arbitrary positive numbers. The properties of embedded subspaces of trigonometric splines are analyzed.

Keywords: two-scale relation, trigonometric $B$-spline, differential operator, wavelets.
