Amplifying Audio
  1. Block Diagram
    1. Signal Source
      1. Outputs audio signal
        1. AC signal
          1. Frequency between 20Hz and 20kHz
            1. Amplitude usually a few millivolts
          2. Pre-Amplifier
            1. Boosts the amplitude
              1. Boosts to levels well above noise level other blocks may add to
            2. Tone Control
              1. Adjusts the frequency balance of the signal
                1. Boosts some ranges and cuts others
                  1. Compensates for imperfect transfer characteristics of the microphone, loudspeaker and human ear
                2. Volume Control
                  1. Varible component that passes a fraction of the current
                    1. Fraction can be between all the signal of nothing at all
                      1. Passes the signal from the tone control to the voltage amplifier
                    2. Voltage Amplifier
                      1. Power Amplifier
                        1. Loudspeaker
