Trellis Noise-Shaping Converters and 1-bit Digital Audio

Document Thumbnail

Just recently, a new type of delta-sigma converter, Trellis Noise Shaping Converter, has been introduced. When it is used to generate a bit stream in 1-bit digital audio format, its trellis structure with Viterbi algorithm enables more efficient use of data bits, which yields better performance in stability, signal to noise ratio and tonal behavior. It solves most of the performance problem caused by harsh non-linearity inherent in 1-bit quantization. This paper briefly examines its architecture and performance. An emphasis is put on its simple and more predictable quantization noise spectrum in comparison with that of conventional modulators.
