| Abstract: | Two different methods of design low pass digital filter have been discussed in detail in this paper,namely the bilinear transformation and the all pole transformation.Each method has its advantages,but it will be seen that all polar design gives superior selectivity,and all polar filter is more flexible than the former approach. |
