Abstract

All of the previously discussed look-ahead techniques are compared in chapter eleven. The outcome of this comparison is that the normal Pruned Tree sigma-delta modulation algorithm is the best choice if the converter is not intended for audio applications, since it offers the highest SNR, very good linearity, and the largest stability at the minimal computational cost. In the case of a high-end application for Super Audio CD, the Pruned Tree sigma-delta modulation algorithm for SA-CD is the best choice because of the constant in-band noise-floor and the higher compression gains that are obtained on the output bitstream.

Fußnoten
1
In the case of the Pruned Tree sigma-delta modulation algorithm for SA-CD the selection cost function is equal to that of the normal Pruned Tree sigma-delta modulation algorithm, but the algorithms uses a different path cost function that includes a measure for the predictability of the bitstream.
