Questions
A telephonic communication service is working at carrier frequency of 10 GHz. Only 10 % of it is utilized for transmission. How many telephonic channels can be transmitted simultaneously, if each channel requires a bandwidth of 5 KHz?
detailed solution
Correct option is C
Only 10 % of 10 GHz is utilized by transmitting. ∴Band available for transmission=10100×10×109=109Hz Now, if there are n channels each using 5 KHz then , n×5×103=109 ⇒n=2×105Talk to our academic expert!
