A sound engineer has an amplifier that takes a 50 mV input and produces a 2 V output. How many decibels of gain does this represent?
💡 Hint: Calculate the voltage gain first, then express it in decibels.
If an amplifier alters an input of 25 mV to an output of 5 V, what is the voltage gain in dB, and how does this gain compare to a hypothetical output of 10 V?
💡 Hint: Make sure to find each gain before comparing.
