FIR Filter, Decimation, Interpolation,
In this paper a general theory of multistage decimators and
interpolators for sampling rate reduction and sampling rate increase is
presented. A set of curves and the necessary relations for optimally designing
multistage decimators is also given. It is shown that the processes
of decimation and interpolation are duals and therefore the same
set of design curves applies to both problems. Further, it is shown that
highly efficient implementations of narrow-band finite impulse response
(FIR) fiiters can be obtained by cascading the processes of decimation
and interpolation. Examples show that the efficiencies obtained are
comparable to those of recursive elliptic filter designs.
