  • Decimation filtering apparatus and method
    Patent number: 6279019
    Abstract: A decimation filtering apparatus using interpolated second order polynomials compensates for a droop caused by a CIC (Cascaded Integrator-Comb) filter. The decimation filter includes a CIC decimation filter for decimation filtering the sampling signal to downconvert a sampling signal; an ISOP filter for monotonically increasing an output of the CIC decimation filter to compensate for a passband droop caused by the CIC decimation filter; a multistage halfband filter including at least one modified halfband filter for half-decimating a signal output from the ISOP filter, thereby downconverting the ISOP filter output signal; and a programmable FIR filter that compensates for a passband droop of a signal output from the multistage halfband filter.
