<p>The <b>amplification factor</b>, also called gain, is the extent to which an analog amplifier boosts the strength of a signal. Amplification factors are usually expressed in terms of power. The decibel (dB), a logarithmic unit, is the most common way of quantifying the gain of an amplifier.
</p><p>In general an <b>amplification factor</b> is the numerical multiplicative factor by which some quantity is increased.
