ELEN 325 HOMEWORK #2 ( Due date: Monday September 18, 2006) 1. Find the transfer function ( T ( s ) = v o ( s ) /v i ( s )) for the following circuits. Assume that the opamps are ideal. (a) v i R 1 C 1 R 2 R 3 C 2 v o R 4 (b) v i v o R 1 R 3 R 4 C 1 R 5 R 6 R 2 (c) v i R 1 R 2 R 3 R 4 R 5 C 1 C 2 R 8 v o R 7 R 6 2. Sketch the magnitude Bode plot for T ( ) and find v o ( t ) for the following cases. (a) For the circuit in Fig. 1(a), R 1 = 1 k Ω , R 2 = 1 k Ω , R 3 = 10 k Ω , R 4 = 5 k Ω , C 1 = 10 nF , C 2 = 1 nF , v i ( t ) = 0 . 1 sin(2 π 10 4 t ) . (b) For the circuit in Fig. 1(b), R 1 = 1 . 5 k Ω , R 2 = 1 k Ω , R 3 = 10 k Ω , R 4 = 2 k Ω , R 5 = 3 k Ω , R 6 = 4 k Ω , C 1 = 10 nF , v i ( t ) = 0 . 5 sin(2 π 10 5 t ) . (c) For the circuit in Fig. 1(c),
