Unformatted text preview: FALL 2008: Put First Letter of LAST Name in the corner ( Otherwise Your HW May Be LOST! ) PRINT: (LAST , Middle, First): EE102: SYSTEMS & SIGNALS HW: # 5 A LATE HW CANNOT BE A HW! Posted: W, November 5 Hand In To Me: M, November 17 Attach This Sheet To Your HW (Otherwise It May Be Lost!) Notations: Let f ( t ) , g ( t ) , t [ a, b ] , be a real signals: f ( t ) , g ( t ) := inner product or scalar product of f ( ) and g ( ) f ( t ) , f ( t ) := || f ( t ) || 2 , || f ( t ) || = f ( t ) , f ( t ) := norm of f ( ) 1. Consider the following signals: f 1 ( t ) = 1 2 , f 2 ( t ) = 3 2 t, f 3 ( t ) = 45 8 ( t 2- 1 3 ) , t [- 1 , 1] Define f ( t ) , g ( t ) = 1- 1 f ( t ) g ( t ) dt (i) Verify whether the signals { f i ( t ) , t = 1 , 2 , 3 } are (mutually) orthonor- mal, that is f i , f j = 0 , i = j, and f i , f j = 1 , i = j, for i, j = 1 , 2 , 3 (ii) Given f ( t ) = e- t , t [- 1 , 1] Calculate: f ( t...
