For a tutorial on sampling continuous-time signals to obtain non-aliased discrete-time signals, see Appendix D. When all signal samples are real, we say . If they may be complex, we write . Finally, means is any integer. Next | Prev | Up | Top | Index | JOS Index | JOS Pubs | JOS Home | Search Page 1 of 2
