Multi-rate systems are popular in DSP, which are used in audio, video processing and communication systems. Using Multi-rate system we can achieve the computation efficiency and improve the system performance. A Multi-rate systems operation involves decimation and interpolation. For a given signal, the method of decreasing the sampling rate is decimation and the process of increasing the sampling rate is interpolation. By cascading the process of decimation and interpolation results, savings in computation and great reduction in hardware complexity is achieved. For the application of Design a Narrow Band Filter for application for signal processing algorithm. To implement such a large order FIR filter in hardware involves large resources and sometime difficult to implement in resource constrained application. Keeping this in view, we have used Multi-rate approach to design the narrowband filter.
