2. The Laplace transform and its applications Apply the Node Voltage method with complex impedances to the following Sallen and Key low-pass filter structure with variable gain, where the buffer amplifier has voltage gain A: C HE R R Mnam V: V.4 Vout C2 and show that the s-domain Transfer Function of the filter is Vout(s) A, Vin(5) RR, GC2S2 + [R,G(1 - A.) + C2(R, + R)]s +1 [Hint: node Vout obeys the equation Vout = A.V.) H(s)
