摘要：

A new linear time-invariant FIR filter which can be programmed to synthetise any fractional sample delay with Lagrange interpolation is presented. An analytic closed-form expression for the coefficients of such an FIR filter is derived. Computer verification is provided for the N=4 case. © 1990, The Institution of Electrical Engineers.
