ISI suppression further?

3.18. The result of a single pulse (impulse) transmission is a received sequence of samples (impulse response), with values 0.1, 0.3, -0.2, 1.0, 0.4, -0.1, 0.1, where the leftmost sample is the earliest. The value 1.0 corresponds to the mainlobe of the pulse, and the other entries correspond to adjacent samples. Design a 3-tap transversal equal- izer that forces the ISI to be zero at one sampling point on cach side of the mainlobe. Calculate the values of the equalized output pulses at times k = 0, ±1..... 13. After equalization, what is the largest magnitude sample contributing to ISI, and what is the sum of all the ISI magnitudes?
