Question

The term decibel is also used in electronics for current and voltage ratios. Gain is defined as the ratio between the signal coming in and the signal going out. The gain, $G,$ in decibels, of an amplifier is defined as $G=20 \log \frac{V}{V_{i}}$ where $V$ is the voltage output and $V_{i}$ is the voltage input. If the gain of an amplifier is 24 dB when the voltage input is $0.2 \mathrm{V},$ find the voltage output, $V$ Answer to the nearest tenth of a volt.

Name: The term decibel is also used in electronics for current and voltage ratios. Gain is defined as the ratio between the signal coming in and the signal going out. The gain, G, in decibels, of an amplifier is defined as G=20 log(V)/(Vi) where V is the voltage output and Vi is the voltage input. If the gain of an amplifier is 24 dB when the voltage input is 0.2 V, find the voltage output, V Answer to the nearest tenth of a volt.
