In this paper we examine the circumstances under which a discrete-time signal can be exactly interpolated given only every M-th sample. After pointing out the connection between designing an M-fold interpolator and the construction of an M-channel perfect reconstruction filter bank, we derive necessary and sufficient conditions on the signal under which… CONTINUE READING
