WebbThis type of filter is difficult to realize in practice and basically the impulse response of perfect continuous filter is sampled to obtain a realizable filter. For this the sampling rate should be double than the symbol rate of the message, i.e. the filter must interpolate the data by a minimum factor of two or more. The raised cosine filter WebbThe raised cosine filter is obtained by using the analytical impulse response and it results in higher filter order. The proposed Raised Cosine filter has been designed using Matlab and Xilinx in which taking filter order 24 and roll off factor 0.5. The design is an efficient realization of RRC filter using two logic families

WebbAs the illustration in Figure 5 demonstrates, the raised cosine has a smooth roll-oﬁ in the time domain, restricting the amount of bandwidth it uses. It also dampens to zero more quickly than the sinc, meaning that it is also more practical to use. Bandwidth and Narrowest Spacing
