Then? 0 votes 0 votes Chandrabhan Vishwa 1 commented Dec 6, 2017 reply Follow Share its not a counter but a random circuit. Then frequecy same as its initial value....but delay occure in this case 2 votes 2 votes Please log in or register to add a comment.
0 votes 0 votes if we are find qunter sequence with the help of reverse user defined method we find 00,01,10,01,10,01,10............ HENCE IT IS MOD 2 COUNTER HENCE THE FREQUENCY f=1/2=.5 Chandrabhan Vishwa 1 answered Dec 6, 2017 Chandrabhan Vishwa 1 comment Share Follow See all 8 Comments See all 8 8 Comments reply Show 5 previous comments kumar.dilip commented Dec 4, 2018 reply Follow Share Yes. If you see in your diagram there will be the loop between only two states only. 0 votes 0 votes Sreyasree Mandal commented Dec 4, 2018 reply Follow Share so the 'N' of MOD-N is always the number of states inside the loop, right? I had started from state 00 and hence counted it too along with 01 and 10 0 votes 0 votes Ashwani Kumar 2 commented Dec 5, 2018 reply Follow Share @Sreyasree Mandal, see the state diagram. 10 and 01 are in loop that's why MOD-2 0 votes 0 votes Please log in or register to add a comment.
