Q. If a frequency multiplier has a multiplication factor of 10, then the increase in noise level due to frequency multiplication is:
  • (A) 10 db
  • (B) 20 db
  • (C) 25 db
  • (D) 15 db
πŸ’¬ Discuss
βœ… Correct Answer: (B) 20 db

Explanation: for a frequency multiplier, the increase in noise power is given by 20 log n, where n is the multiplication factor of the multiplier. substituting in the below equation, increase in noise level is 20 db.
