Notes:
•
Only new circuits (circuits that are not published recently)
are described.
•
Figures can deviate slightly from the actual situation, due
to different set executions.
•
For a good understanding of the following circuit
descriptions, please use the wiring, block (see chapter
9. Block Diagrams) and circuit diagrams (see chapter
