1kΩ + Vi 0.1uF+ V. Fig. 2a a) Given a circuit shown in Fig. Q2a, determine the mathematical expression for the magnitude of the ratio V/Vi (in dB) in terms of operating frequency fand cutoff frequency fi. . [10 marks] b) Determine the value of cutoff frequency fi for the circuit in Fig. Q2a. [2 marks] c) A certain RC circuit has a critical frequency at fo = 1,000 Hz, above which the attenuation is approaching 0 dB. What is the dB attenuation at 100 Hz? Explain your answer. [1 + 4 marks]
