K. Babulu · 2012
Abstract — Multi-rate Signal Processing consists of using multiple sample rates within a system to achieve computational efficiencies that are impossible to obtain with a system that operates on a single fixed sample rate. In Multi-rate Signal processing studies used in Digital Signal processing systems include sample rate conversion. This technique is used for systems with different input and output sample rates, but may also be used to implement systems with equal input and output rates. This paper presents the proposed reconfigurable architecture of Multirate signal processing circuits such as Interpolator and Decimator with low complexity.
