1-BIT AMPLIFICATION FOR BETTER AUDIO QUALITY
The CDs provide enough sound quality for most of the music lovers but many of them demand more quality to reach that of the real live performance. for this purpose complete range of analogue signals must be reproduced without much deterioration in the signal quality. Even the analogue records could not achieve this quality aim. The 1 bit amplification can rectify all these errors and can bring noticeable quality improvement.
In the block diagram, the input is given to a oversampling digital filter. The analogue signal and the input are given to the 7th order delta sigma modulator. From this , the output goes to a fixed voltage high speed switching circuit. It is then amplified and then given to a low pass filter network which outputs to the speakers.

The production of sound in depth is achieved by the delta sigma modulation coding technology.

MERITS
This technology is better than the multibit amplification. We can achieve true sound with better time resolution. The sound can be produced with depth. Also it is small in size.
