N. Mikami, Masaharu Kobayashi, Y. Yokoyama · IEEE Transactions on Signal Processing · 1993
The relationship between Hornor's method for polynomial evaluation and a first-order recursive filter with error feedback (EFB) is described. It is shown that EFB is a useful technique for reducing the roundoff errors that occur in evaluating a function by polynomial approximation.>
