Let say we have to Design mod-8 counter i.e 000 to 111. so we need 3 bit to represent i.e 3 FF 

for Mod N

2x = N 

x = ceiling (log2N)

I have a doubt: if it is possible to form mod 8 counter using 3 FF. Why do we use Ring Counter or Johnson counter?
to make mod8 ring counter, we will need 8 FFs.
this is for asynchronous counter
