To understand how the Monitor works, it is best to know what each circuit
does and how each circuit relates to the other circuits. The Block Diagram is
presented in a simplified view and a comprehensive view to accomplish the goal of
understanding the whole unit. Once the general picture is clear, the complexity of
each circuit will be easier to understand.
The Circuit Description is also written in two views, a simplified view and a
detailed view to help give the reader a clear understanding of what each
component does. This understanding is most helpful for the more complex
problems or multiple problems that sometimes occur.
