You can design several classes of maximally flat FIR digital filters, which include linear-phase and nonlinear-phase filters of even and odd orders, generalized halfband filters, and fractional delay systems known as Lagrange interpolators. What you get are filter coefficients in rational numbers (not decimal numbers), and so they are accurate.
