(a) Explain what is the difference between a Hartley and a Colpitts oscillator [4 marks] (b) Design and draw an RC phase shift oscillator circuit that produces a sinusoidal output with a frequency of 5 kHz. Assume the capacitor C = 0.01 uF. [9 marks) (c) State three advantages of RC phase shift oscillators [6 marks) (d) Design a Wein-bridge oscillator that oscillates at the frequency of 25 kHz. Assume the capacitor C1 = C2 = 0.001 uF. [6 marks)
