  4. 7.3 The configuration of the figure is a R1 R2 C

  5. (a) Precision integrator (b) Hartley oscillator (c) Butterworth high pass filter (d) Wien-bridge oscillator [2000: 1 Mark] 5

  6. 6.8 Assertion (A): Wien bridge oscillator is generally used as a variable audio frequency oscillator. Reason (R): By varying either the capacitor or resistor value in one of the arms of the bridge, the frequency of the Wien bridge oscillator can be varied 6

  7. of Crequired for sinusoidal oscillations 7.7 The value of frequency 1 kHz in the circuit of the figure is 2.1 KS2 out 1 KS2 (a) (b) 2 .F 2 (C)2rVe [2004 2 Marks]

  8. C:1/ c_

  9. 7.2 Value of R n the oscillator shown in the given figure. So chosen th just oscillates at an angular frequencies of"ay. The value of and the required value of Rwill respectively be 1O0 kS2 10 mH 1 kS2 (a) 105 rad/sec, 2 >< 104 (b) 2 >< 104 rad/sec, 2 >< 104 (c) 2>< 104 rad/sec, 105 (d) 105 rad/sec, 105 L1996 : 2 Marks] 9
