Homework Assignments: Please read and be prepared for a quiz on chapters 6&7&8 from your books on Saturday July 11 th. We will talk about those chapters after this quiz. We need to make up one day off on 4 th of July, so we must go faster to cover all materials that we should learn for this semester. Instrumentation I - Session 3
