2.1 State five properties of a real operational amplifier and give typical values. [5] 2.2 Suggest one technique that can be used in improving the input and output resistance of an operational amplifier. Support your answer with basic equations of [5] how this can be achieved in practice. 2.3 Design an amplifier circuit that will give a gain that can be adjusted from 0 to 150. Your answer should include a circuit diagram and suitable resistance values for the [6] circuit. 2.4 Design a circuit that will produce an output voltage vo given by the following relationship: vo= 2v₁ +5v₂ - 6v3 [9]
