Name:_____________________________________ EE 3120 Test # 2 SSN:_______________________________________ Summer 2004 Some trig identities: 2 1 cos ( ) (1 cos2 ) 2 α = + 1. Considering that we can perform a complete circuit analysis in the time domain, (for an RLC circuit for example) why is the Laplace transform sometimes used in instead? 2. Given f ( t ), find F( s ) and the region of convergence of s . a. 2 ( ) 1 sin t f t t e t - = + + b. 2 ( ) cos (5 ) f t t = 3. Use the initial value theorem to determine the value of (0 ) f + for the following transfer function. 2 3 2 (3 6)( 2) ( ) ( 5 7 3) s s H s s s s s - - = - + +
