The process of increasing the sampling rate of any signal by a factor is known as interpolation. This paper presents the effective and efficient implementation of multistage implementation of digital interpolator using half band filters. The single stage filters are efficient for lower order interpolation factors but for higher rate change which is required in modern digital communication systems like wideband code division multiple access, worldwide interoperability for microwave access single stage implementation does not gives efficient response. For these applications a multistage implementation of the interpolator is preferred. But multistage implementation increases complexity of the overall system. This complexity can be reduced considerably by using half band filters. All this has been done with the help of the Agilent's advanced design software.
