Abstract -
In this paper we proposed an efficient structure for sampling rate conversion by rational factor of L/M, where L is upsampling factor and M is downsampling factor. In this method, the coefficient symmetry of the linear phase filter is used. In this way, the number of required multiplications per output sample is reduced. For implementation we use linear phase FIR filter. The symmetric FIR filter has shown reduction in multipliers as compared to conventional polyphase implementation.
