-
An antenna having resonant frequency f and having a Q factor of 20 can handle a bandwidth of 10 MHz then f is—
-
- 10 MHz
- 20 MHz
- 200 MHz
- None of these
Correct Option: C
We have important relation of quality factor, bandwidth and cut-off frequency
| Q = | ⇒ | = 20 ⇒ f = 200 MHz | ||
| BW | 10 × 106 |
where,
Q = quality factor
f = resonance frequency
BW = bandwidth
