Share:
- 1To adjust the resonant frequency of the circuit by changing the tuning dial.
- 2To allow the A.C. signal to pass freely while blocking any D.C. bias voltage from affecting the subsequent stage.✓
- 3To increase the inductive reactance of the following stage.
- 4To block the A.C. signal and allow only the D.C. component to pass to the next stage.
Correct answer
To allow the A.C. signal to pass freely while blocking any D.C. bias voltage from affecting the subsequent stage.
