Audio signal converting process for e.g. audio signal digital amplification application, involves calculating cost function to mark output candidates and their corresponding changes minimizing cost function

摘要

The process involves initializing a number (N) of output candidates and selecting a number (K) of probable changes corresponding to the output candidates. A cost function is calculated to mark the output candidates and their corresponding changes minimizing the cost function. Candidates, that minimize the cost function, are selected from the group of output candidates by a candidate selection block (9).
