Abstract

An approach to implement the interpolation function by means of Lagrange interpolators is given. The proposed architecture does not require high-frequency multipliers. With respect to conventional sinc filters of a comparable order, the response of Lagrange interpolators is better both in the passband and in the stopband, while the proposed implementation requires only a small increase in circuit complexity
