Synchronous Counter Circuit
In the given synchronous Counter circuit, initially all Outputs are Reset. It is required to replace FF2 with AB Flip Flop. The FF2 inputs would be: A. A = Q1 and B = Q1' B. A = Q1' and B = Q1' C. A = Q1.Q0 and B = Q1.Q0 D. A = Qo' and B = Qo'

Johnson Counter Doubt
I have found this statement about Johnson Counter : A Johnson counter requires decoding gates whereas a ring counter doesn't. As with the binary counter, one logic gate (AND gate) is required to decode each state, but with the Johnson counter, each ... to implement it? The reference link is here: https://www.doc.ic.ac.uk/~nd/surprise_96/journal/vol4/cwl3/report.html#johnson
