The function of ferrite antenna is to_________________?
Correct answer: C. Increase the Q of tuned circuit
- A. Reduce stray capacitance
- B. Stabilise d.c. bias
- C. Increase the Q of tuned circuit
- D. Reduce noise
Explanation
A ferrite rod increases the inductance and magnetic flux linkage of the coil, allowing a compact tuned antenna with a higher Q and better selectivity. Thus it increases the Q of the tuned circuit.
