Question

What is the conversion factor for 1 decibel (dB) in terms of nepers (np), as stated in the document?
Options
A 1 dB = (1/2)ln(10) np
B 1 dB = (1/10)ln(10) np
C 1 dB = (1/20)ln(10) np
Correct Answer
D 1 dB = ln(10) np
Correct Answer

Option C is the correct answer.

Detailed Explanation

The document states: '0.1 dB = (1/20)ln(10) np'. Since 0.1 dB is one decibel, this is the correct conversion factor.
