Figure 11 is a Tow-Thomas low-pass filter topology. R₂ C₁ Rf W R₁ Vin Vout Figure 11 (a) What is the DC gain of the filter? (b) If R3, R2, Rf, R4, R5 = 10k Q and C₁, C₂ = 10nF, what is the low-pass cut-off frequency? (c) At what point in the circuit can a band-pass output be obtained? (d) What aspect of the filter low-pass response does RF control? (e) If Rf is open circuit what signal would be expected at Vout ? R3 C₂ R4 R4
