- TITLE:
-
A double binary-tree FIR filter form and the
corresponding low-sensitivity IIR bandpass/bandstop
structure
- AUTHORS:

- ABSTRACT:
- An FIR filter comprising back-to-back binary trees,
each using multiple-sample delay blocks, offers
advantages (1) for rate-changing filters, (2) when
block delays are especially hardware efficient, and
(3) when replacing block delays with allpass sections
to create an IIR filter. In the latter case, the peak
group delays of the allpass sections approximate the
several distinct delays of the blocks replaced. With
allpass sections fixed, the combining weights are
easily optimized.
