thumb|Amplification means increasing the amplitude (voltage or current) of a time-varying signal by a given factor, as shown here. The graph shows the input v_i(t) (blue) and output voltage v_o(t) (red) of an ideal linear amplifier with an arbitrary signal applied as input. In this example the amplifier has a voltage gain of 3; that is at any instant v_o(t) = 3v_i(t)\,
