Class D Amplifier

Analogue circuits are less efficient and produce more waste heat that digital circuits.
The Class D Amplifier converts analogue audio into a switched pulse width modulated digital signal at a frequency well above the range of human hearing (at least 44kHz). The amplifier works with close to 100%efficiency. The high frequency information is filtered out before the output is fed to the loudspeakers.
