Digital Power Amplifiers
High Power No Longer Means High Heat Dissipation
PWM (Pulse Width Modulation) Amp
In the PWM amplifier system, a PWM signal is created according to the signal level of the audio signal waveform at each point in time. This arrangement results in a small power loss when output is large, making it possible to improve efficiency. However, a low pass filter must be inserted in the output stage in order to recover the original audio signal waveform from the PWM signal. This makes it impossible to avoid deterioration in the signal's frequency response, distortion, etc.
