Question 3 Figure 10 represents the well-known Sallen-Key filter circuit. VI 24 V₁-Z1 Vo R3 Figure 10 (a) List three types of filter which can be realised with this circuit. (b) If R3 is an open circuit, R4 is short circuit, Z₁, Z₂ = R and Z₁ Z3 = (1/60 C) determine the filter functionality obtained. (c) In (b) above, if R=10 k2 and C= 10nF, determine the approximate frequency at which Vo/Vi is no longer -1. (d) What two effects will occur if R3 = R4 =R in (b) above? 23 Vp Vn -M www R4 [6%] [6%] [8%] [5%]
