Answer:

decibel gain is 10 db

Explanation:

given data

voltage v1 = 5 volts

voltage v2 = 15 volts

to find out

decibel gain

solution

we have given that 5 volt voltage that is increase to 15 volts

we know here decibel gain formula that is

decibel gain = 20 log(v2/v1) ....................1

put here value of v1 and v2 in equation 1

decibel gain = 20 log(15/5)

decibel gain = 20 log3

decibel gain = 20 × 0.4771

decibel gain = 9.54 db = approx 10 db

so decibel gain is 10 db
