Lab experiment date: October13,2010 Name: Simran Ahuja Lab Day: Wednesday Lab time: 1:30pm Lab instructor: Poornima Lab number: 8 Title of experiment: Counters Write a technical response to each of these questions. For each of the following discussions address questions like, “how does the circuit determine when to recycle? How does it determine which state to recycle to? Which state transitions are synchronous? Which state transitions are asynchronous? How does this circuit count? Discuss the method used to modify the 0-4 counter. In order to determine the circuit we first use mod number and see what is required.Then to make the new bdf of circuit that counts 0-3 we add logic gates to it so that we have four outputs.To make a circuit that counts from 0-3 we add a NAND gate to the signal going out and connect the NAND gate from the other side to the CLR.The circuit determines which state to recycle by

Unformatted text preview: seeing the number of output it needs.The circuit remains asynchronous until the clock becomes active.Synchronous state is every cycle of the clock. Discuss the method used to modify the 3-7 counter. In order to make a circuit which determines and reads 4-7 we must know how to use mod numbers.Then to make the bdf circuit we use three NOT gates attached to each signal going out.And a NAND gate is also connected to these NOT gates which is further connected to one of the CLR.The CLR is preset in order to read 4-7.The circuit determines the state of recycling by seeing the number of outputs it needs.Synchronous state is with every state of cycle.The circuit remains asynchronous until the clock becomes active.
