Monotonicity is a desirable specification, it's not a type of
converter.

No, this would not be an A/D converter.  This would be a control
system (which might use an A/D converter).

It's a combinational logic circuit.  Physically, it would most
likely be implemented with a PAL.

In a rough sort of way.  The second-last lecture covered
different types of electric motors and described some
applications.

It was covered in class (but perhaps you blinked).
