Efficient real-time interpolation for D/A conversion
J. de Carvalho, J.V. Hanson · Electronics Letters · 1981
Four interpolation schemes using small sample sets are considered for real-time D/A conversion applications. Evaluation, for sampling rates near the Nyquist limit, is based on a mean-square-error criterion. Hardware suitability is considered with respect to the number of operations per interpolation and degree of parallelism.
