In any communication system, it is desired to convert very high sampling frequency to processor frequency. This can be implemented by using efficient use of Multirate Filters. In this paper, the Multi rate filters have been implemented very effectively on FPGA Platform. Also, it has been shown that how performance of Multi rate filters can be improved using different techniques at different sampling rates. The filter structures suggested here have wide applications in the field of ADC (Analog to Digital Converter), DUC (Digital Up Converter)/DDC(Digital Down Converter) and in almost every stage of communication system wherever convolution is being done. The results also show that proposed multi rate filter structures can be used very effectively and efficiently in designing and development of very large scale integration of Digital communication system.
