RS NOR FLIP-FLOP Name: ___________________ Purpose: To investigate an RS NOR flip-flop which is one of the simplest electronic storage devices. Theory: Read textbook p 257-261 When given a certain input signal, the output remains high or low indefinitely. The output are labelled Q and Q and hence should be complements. When the inputs are both high, the outputs are not complements. When moving from two high inputs to two low inputs, the output is not predictable. It produces an unpredictable state 1, 0 or 0, 1. This is called the forbidden state. R S Q 1 4 Q 2 3 5 6 Procedure: Draw your wiring on your breadboard simulator before you wire it on the breadboard. (Don’t forget your labels) Save it on a disk Include a printout of a MM Logic circuit diagram. Page 1 of 3
