In practice, voltage gain is expressed______________?
Correct answer: A. In db
- A. In db
- B. In volts
- C. As a number
- D. None of the aboveGet Study Guides
Explanation
Voltage gain is commonly expressed in decibels using 20 log10(Vo/Vi), which conveniently represents very large gain or attenuation ratios. Volts describe voltage level, not gain itself.
