Description

The SP432S23RG is an electronic component model in the IC Chips product category.

The HSP43216 Halfband Filter is a versatile component that combines quadrature up/down conversion circuitry with a fixed coefficient halfband filter processor. It can be configured to operate in four different modes: decimate by 2 filtering of a real input signal, interpolate by 2 filtering of a real input signal, fS/4 quadrature down conversion of a real input signal followed by decimate-by-2 filtering to produce a complex analytic signal, and interpolate-by-2 filtering of a complex analytic signal followed by fS/4 quadrature up conversion to produce a real valued output.
