Honor Code Statement: I have neither given nor received help on this quiz. Initials 1 of 2. (a) What is the expression for the voltage gain V o /V i at very low frequencies? V o /V i = ( R 2 + R 3 ) /R 1 (b) What is the expression for the voltage gain V o /V i at very high frequencies? V o /V i = R 3 /R 1 (c) Solve for the transfer function T ( s ) = V o /V i . Use the two-terminal impedance theorem to write T ( s ) = R 2 + R 3 R 1 1 + R 2 k R 3 Cs 1 + R 2 Cs (d) What is the expression for the pole frequency of T ( s ) in rad / s ? ( R 2 C ) 1 (e) What is the expression for the zero frequency of T ( s ) in rad / s ? [( R 2 k R 3 ) C ] 1 (f) Sketch and label the straight line Bode magnitude plot for | T ( ) | . Low pass shelving
