we address the design of economical
recursive generalized comb filters (GCFs) by proposing an ef-
ficient technique to quantize the multipliers in the z-transfer
function employing power-of-2 (PO2) terms. GCFs are efficient
anti-aliasing decimation filters with improved selectivity and
quantization noise rejection performance around the so-called
folding bands with respect to classical comb filters. The proposed
quantization technique guarantees perfect pole–zero cancelation
in the rational z-transfer function of the GCFs, thus totally
avoiding instability problems. Moreover, we propose the use of a
simple droop compensator for the sake of recovering the passband
droop distorting the useful digital signal in the baseband. A design
example is proposed with the aim of showing the application of
the proposed technique, and a practical architecture of a sample
third-order GCF is discussed.
