Oscillator MCQs

41. The basic hartley oscillator uses

1. one inductor and two capacitors
2. a centre tapped inductor and a capacitor
3. two capacitor
4. tickler coil

42. The primary advantage of a crystal oscillator is

1. It can oscillate at any frequency
2. It gives a high output voltage
3. Its frequency of oscillation remains almost constant
4. It operates on a very low dc supply voltage

43. Feedback factor at the frequency of oscillation of a Wien bridge oscillator is

1. 3
2. $\frac{1}{3}$
3. $\frac{1}{29}$
4. $\frac{3}{29}$

44. The required gains of the amplifier for sustain oscillations in Wien bridge oscillator are

1. |A| = 3, |B| = 1/3
2. |A| = 2, |B| = 1/3
3. |A| = 3, |B| = 1/2
4. |A| = 1, |B| = 1
