  5. 6.2/ A Hartley oscillator is used for generating (a) very low frequency oscillation (b) radio-frequency oscillation (c) microwave oscillation (d) audio-frequency oscillation [ESE-1999] 5


  6. 6.3 In every practical oscillator, the loop gain is slightly larger than unity and the amplitude of the oscillations is limited by the (a) magnitude of the loop gain (b) onset of non-linearity (c) magnitude of the gain of the amplifier (d) feedback transmission factor [ESE-2000]


  7. 6.15 Which one of the following oscillators is used for the generation of high frequencies? (a) R-C phase shift oscillator (b) Wien bridge oscillator (c) L-C oscillator (d) Blocking oscillator [ESE-2009


  8. 6.22 In a sinusoidal oscillator, sustained oscillations will be produced only if the loop gain (at the oscillation frequency) is (a) Less than unity but not zero (b) Zero (c) Unity (d) Greater than unity [ESE-20161] 8


  9. 6.13 Assertion (A): All practical R-C phase shift oscillators generate sinusoidal oscillation with some amount of amplitude distortion, which cannot be avoided Reason (R): The amplitude distortion of a sinusoidal oscillator is controlled by the onset of non-linearity of the amplifying device (a) Both A and R are true and R is the correct explanation of A Both A and R are true but R is NOT the correct explanation of A (b) (c) A is true but R is false (d) A is false but R is true [ESE-2o06]
