Answer:
876100
019343
Explanation:
10s complement of a decimal number is obtained by the following process:
- Obtain 9s complement ( Subtract each digit by 9)
- Add 1 to the result
1) 123900
9s complement => (9-1)(9-2)(9-3)(9-9)(9-0)(9-0)
= 876099
Adding 1 , 10s complement of 123900 = 876100
2) 980657
9s complement = (9-9)(9-8)(9-0)(9-6)(9-5)(9-7)
= 019342
Adding 1 , 10s complement of 980657 = 019343
Answer:
69.54
Explanation:
A power ratio of 9000000:1 corresponds to 69.54 dB.
The calculation is presented below:
Formula for calculating Power ratio (db) = 10 * log [P(out)/P(in)]
Since the given ratio is 9000000:1, substituting in the formula gives us 10 * log (9000000/1)
Note that log 9000000 = 6.954
Therefore, 10 * log (9000000/1) = 69.54
Hence the required power ratio in db is 69.54 db.
