2. Consider a unit-energy root-raised-cosine (RRC) pulse which spans over 8 symbol durations. We take 10 samples per symbol (sps) from this RRC pulse. Write an RRC filter function that employs pulse-shaping using the RRC pulse described above. (If there is a single symbol and s=[1 0], the energy of the corresponding length-81 samples vector should be equal to 1.) The parameters of the RRC pulse are roll-off factor, span, and samples per symbol. You should write your pulse-shaping function according to the prototype given below txFilt = myRRCFilter(s, rf, span, sps) where txFilt is the pulse-shaped signal (transmitted signal), s denotes the transmitted symbols, rf is the roll-off factor, span is the span of the filter, and sps is the samples per symbol.
