On the use of interpolated second-order polynomials for efficient filter design in programmable downconversion.

On the use of interpolated second-order polynomials for efficient filter design in programmable downconversion.

Interpolated second-order polynomials (ISOPs) are proposed to design efficient cascaded integrator-comb (CIC)-based decimation filters for a programmable downconverter. It is shown that some simple ISOPs can effectively reduce the passband droop caused by CIC filtering with little degradation in ali...
