Abstract :
A new approximation to the Gaussian-filter response is presented that uses a power-series-economisation technique with Cheby¿shev polynomials of the first kind. For high-order filters, the new method appears to yield a closer approximation to the Gaussian response than is given by the Taylor or Laguerre approximations.
