Applications Of Multirate Signal Processing. In digital signal processing we commonly need to change the sampling rate of the signal to achieve a more efficient system. Applications of multirate signal processing fundamentals decimation interpolation resampling by rational fractions multirate identities polyphase representations maximally decimated filter banks aliasing amplitude and phase distortion perfect reconstruction conditions digital signal processing p 2 25.
As mentioned in 3 multirate systems find application in communications speech processing spectrum analysis 6 radar systems and antenna systems. A thesis submitted in partial fulfillment of the requirements for the degree of. In this tutorial two sections are devoted to a review of applications.

In digital signal processing we commonly need to change the sampling rate of the signal to achieve a more efficient system. Incorporating more than one sampling rate within a system is called multirate signal processing. This article reviews the application of multirate dsp in achieving a more efficient a d conversion and clarifies why we need different sampling rates within a single system.
