Question

(a) The circuit shown below is a LC parallel resonant circuit. Calculate the resonant frequency fo, inductive reactance X₁, capacitive reactance Xc, flow of current IL,through the inductor L and Ic, through the capacitor C, Q factor, tank impedanceZtank, and the total current flow, IT.[8 Marks]

(b) Sketch a basic circuit diagram of the Hartley Oscillator that uses a high-pass filter-for its feedback network. Also, give a brief detail of its working by drawing the-amplitude and phase response of the network.[10 Marks] (c) Sketch a schematic diagram of a transformer-coupled oscillator with a tuned-secondary circuit to explain how this oscillator generates oscillating frequency.Also, sketch its amplitude and phase response curve.[7 Marks]
