Circuits, systems and methods for volume control in low noise 1-bit digital audio systems |
摘要 |
A method of amplitude control in a 1-bit digital system includes the step of scaling the stream of 1-bit data by a scaling factor corresponding to a selected output amplitude. The scaled data is modulated and the resulting modulated, scaled data is converted from digital to analog form.
