Abstract : In this paper we present a novel method for scaling of multistage interpolators. When a signal is upsampled it becomes Cyclo-Wide-Sense Stationary (CWSS) which prevents the use of common algorithms for scaling. Our method is based on multirate identities and polyphase decomposition and avoids these problems.
