(a) Find the transfer function ( ) ( ) ( ) 2 1 T s V s V s = and the corresponding gain function ( ) T j . (b) Find the DC gain ( ) T , infinitefrequency gain ( ) T , and the cutoff frequency c . (c) Does this circuit have a lowpass, highpass, bandpass, or bandstop frequency response? (d) Draw the straightline approximation and use it to estimate the circuit gain at frequencies: 1 2 c = , c = , and 2 c = .
