If the band width is 1.6 x 10^12 Hz, how many communication

• Communication Systems

If the band width is 1.6 x 10¹² Hz, how many communication channels can be obtained with 16 KHz band width radio signal?

1. 10⁸
2. 10¹¹
3. 10¹⁰
4. 10¹⁵

Answer

Bandwidth = 1.6 x 10¹² Hz = 16 x 10¹¹ Hz

Bandwidth of one signal = 16 x 10³ Hz

Therefore,

Number of communication channels = (16 x 10¹¹)/(16 x 10³) = 10⁸

The correct option is A.
