Figure 10 represents the well-known Sallen-Key filter circuit. Vf Z4 V₁-21 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 Z4 = Z3 = (1/@ C) determine the filter functionality obtained. (c) In (b) above, if R =10 kN and C= 10nF, determine the approximate frequency at which Vo/V₁ is no longer ~1. (d) What two effects will occur if R3 = R4 = R in (b) above? Z2 EZI Vp Vn + ww R4 Vo
