HSP43216 Data Sheet January 1999 File Number 3365.7 Halfband Filter The HSP43216 Halfband Filter addresses a wide variety of applications by combining fS/4 (fS = sample frequency) quadrature up/down convert circuitry with a ﬁxed coefﬁcient halfband ﬁlter processor as shown in the block diagram. These elements may be conﬁgured to operate in one of the four following modes: decimate by 2 ﬁltering of a real input signal; interpolate by 2 ﬁltering of a real input signal; fS/4 quadrature down conver.
