A certain wireless channel has the following impulse response: h(t) = k1(t) + k2(t ) (a) Determine the frequency response of the overall system if the transmit and receiver lters are given by G(f) and C(f). (b) Determine the frequency response of the transmit and receive lters if the system is designed to completely mitigate the ISI by using an ideal Nyquist pulse. Assume that the channel is compensated solely at the transmitter. (c) Determine the frequency response of the transmit and receive lters if the system is designed to completely mitigate the ISI by using a raised cosine pulse with a roll-o factor = 0:5. Assume that the channel is compensated equally at the transmitter and receiver. (d) Determine the frequency response of the transmit and receive lters if the system is designed to completely mitigate the ISI by using a full raised cosine pulse. Assume that the channel is only compensated solely at the receiver.

a  social news website  is an  internet  website  that features  user-posted stories. such stories are ranked based on popularity, as voted on by other users of the site or by website administrators. users typically comment online on the news posts and these comments may also be ranked in popularity. since their emergence with the birth of  web 2.0, social news sites have been used to link many types of information, including news, humor, support, and discussion. all such websites allow the users to submit content and each site differs in how the content is moderated. on the  slashdot  and  fark  websites,  administrators  decide which articles are selected for the front page. on  reddit  and  digg, the articles that get the most votes from the community of users will make it to the front page. many social news websites also feature an online comment system, where users discuss the issues raised in an article. some of these sites have also applied their voting system to the comments, so that the most popular comments are displayed first. some social news websites also have a  social networking  function, in that users can set up a user profile and follow other users' online activity on the website.
