PRACTICAL 6: STATE MACHINES AND CODE GENERATORS

AIM: INTRODUCTION: This laboratory is about the design, implementation, and testing of a state machine counter and a pulse train generator. The circuits will use JK flip-flops and logic gates to implement the necessary logic operation of the problem. The ICs used are the 7474 JK flip-flops and the 7400 NAND gates . The state machine counter has to follow a State Transition Diagram ...

When policy planners are putting together a plan for developing reading and writing assessment, they are naturally going to need multiple types of artifacts in order to yield a complete picture of each student’s progress (Ludwig 2003). This is particularly true when dealing with students in the primary grades, because they are often far from sophisticated in their interpersonal communication, which means that gaining an accurate picture can be even more difficult than it is in secondary grades (Yelland, Lee, O’Rourke & Harrison 2008). Teachers are taking on a number of different strategies to integrate the newest technologies ...

555timer

Introduction The 555 integrated circuit (chip) is used in a variety of timer and oscillator applications. A 555 timer is used to provide time delays and oscillations and as a flip-flop element. The device has additional terminals provided to trigger or resetting purpose (Nair, 2006). During the time delay operation mode, time is precisely controlled by an external resistor and capacitor. While working as an oscillator, the duty cycle and the frequency are accurately regulated by two external resistors and a capacitor (Brumbach, & Clade, 2003). 555 is triggered and reset on falling waveforms. A typical 555 timer IC is ...
