Hi

I came across this question in one of the websites. Can anyone help me with the answer?

Design a circuit which generates the following pattern:

1000
0100
0010
0001
0010
0100
1000

Thanks
Deepa
 

hi,

One simple way to do this is FSM.

other way is design updown counter and handle up count and downcont care fully it is not a big deal.

This can be easily done with synchronour counter design techniques using PS, NS table.
Refer any basic dugital books which explains counter design techniques.

Hope it helps.

hi Shitansh

i understand that it can be done on the same model as up-down counter.. but that will require an additional input.. can this be done without an external input?

Hi Deepa,

You need only theree inputs Clock, Reset and start, if you dont want to use third input start then also you can do it but in that way your module will generate continuous pattarn you want and you do not have control of start and stop.

Also as Syswip suggested you can do this by shifting, although I haven't take a look at code, but you can use that option also.
