Question

draw and explain 4 bit Johnson counter? how it is better than ring counter​

Answer 1

Difference Between Ring Counter and Johnson Counter

the inverter output of the last flip-flop is connected back as the input to the first flip-flop.

In-ring counter, the no.of input clock pulses given to the flip-flops are equal to the no.of stages.

In johnson’s counter, the no.of input clock pulses divide by a factor of twice equal to the no.of stages. That means the MOD of the n-bit johnson counter is ‘2n’.
