This paper introduces polynomial impulse response time-varying FIR filters for reconstruction of two-periodic nonuniformly sampled signals. The main advantages of using these reconstruction filters are that on-line filter design is avoided, and filters with fixed dedicated multipliers can be used in an implementation (except for a few general multipliers). This is in contrast to existing filters that require on-line design as well as general multipliers in the implementation. By using the proposed filters, the overall implementation cost can therefore be reduced dramatically in applications where the s ampling pattern changes now and then
