- Shing,
-
- This is not an especially challenging task for any engineering
- type person to solve. (You'll probably find an optimized and completely
- detailed solution to this if you just walked into your school's EE Department
- - most Sophmore or Juniors are knowledgeable enough to not botch something
- as simple as this up!)
-
- But what they may miss is that you've defined your "6" and "b"
- to look exactly alike!
