VIRHEITÄ / ERROS(updated 22.3.2000) Book, page 396, table 5.3 (Summary of F-series and transform expressions): ======================================= | x(t) | a_k || x[n] | a_k | x(t) | X(jw)* || x[n]* | X(e^jw) --------------------------------------- X(jw) = 1/2pi int_ ... and x[n] = int_ are mixed. The boxes marked with * Correct: X(jw) = integral{ x(t) e^(-jwt) dt} x[n] = 1/2pi integral{ X(e^(jw)) e^(jwn) } http://www.cis.hut.fi/teaching/T-61.140/virheita.shtml tik61140@cis.hut.fi Tuesday, 20-Jan-2004 11:56:15 EET |
