Decoders are covered in Chapter 4.
Week 4 2/14	Monday lecture another way to draw NANDs and NORs... relationship between if ( a==b ) { ... } and logic gates active-low/active-high signals and circuits decoders with active-low outputs: most common! Exercise: Implement f = Σ(1,3,4,5) with a decoder with active-high outputs Exercise: Implement f = Σ(1,3,4,5) with a decoder with active-low outputs decoders with an enable input cascading decoders designing a 3-to-8 decoder with the 4-to-10 7442 decoder Lab #4 Wednesday The Multiplexer circuit The RS flipflop Friday Catch-up day Lab #4 Homework #4 and Solution
Week 5 2/21	Monday lecture the RS Flipflop Timing Diagrams Exercise: Design a majority voter that remembers when a fault occurs. First design a simple one that keeps track of the fact that a fault occurred in the past. Add a reset button to reset the fault signal. Then modify your design so that the majority voter not only remembers that there was a fault, it also remembers the Id of the faulty device. The oscilloscope Sampling Periodic signals Frequence Peak-to-peak voltages Trigger: Rule = always trigger on the slower of two signals!

Characteristic Table of the D-Flip-flop State diagram State table Activation table Lab Lab #6 Wednesday Exercises on FSM Friday Lab #6	Read Chapter 5 The chapter introduces several flip-flops. We'll look at the JK briefly in class. The chapter also introduces two different approaches to designing finite state machines: the Moore machine and the Mealy machine. We're concentrating here on the Moore machine, for which the output is a function of the present state only. This is the simplest and more widely used model.
