The gain of an amplifier is expressed in db because_____________?
Correct answer: C. Human ear response is logarithmic
- A. It is a simple unit
- B. Calculations become easy
- C. Human ear response is logarithmic
- D. None of the above
Explanation
Decibels use a logarithmic scale, which corresponds approximately to the logarithmic response of human hearing over a wide range of sound levels. This makes large power or voltage ratios easier to express.
