On the equivalence between Gamma and Laguerre filters

  title={On the equivalence between Gamma and Laguerre filters},
  author={Tomas Oliveira e Silva},
In this paper we prove the equivalence between the Gamma and Laguerre filters. Applying the optimal conditions for Gamma filters, which are easy to obtain, we arrive at the optimal conditions for Laguerre filters. Curiously, fhese conditions are the same as those of a truncated Lagiirrre series approximatiou, which corresponds to tlie usage of an impulse as the input of the Laguerre fi1tr.r. We illustrate these results with an example, where we also investigate the relativc merits of hoth… CONTINUE READING
