Question

Statement A: Satellite communication uses different frequency bands for uplink and downlink
Statement B: Bandwidth of video signals is 4.2MHz

• A. A is true but B is false
• B. A is false but B is true
• C. A and B are false
• D. A and B are true

Answer 1

The correct option is D A and B are true

Satellite communication uses different frequency bands for uplink and downlink to avoid interference. video signals have large data, so to transfer these signals we need high bandwidth, like 4.2 MHz.
