Explain Mod-3 Counter with circuit diagram and truth table.
A counter has a natural count of where n is the number of flip flops in the counter. Counter of modulus of 3 is Mod-3 counter.
From the above diagram and truth table,we see that after two clock pulses is low(0) and is high (1) . is fed back to .
If =high (1) then =low(0)=>=0,=1
At the third clock pulse the first flip flop will remain in the reset state. will remain zero.here ,=1,second flip flop will also remain in reset state.
Since is fed back to ,the counter resets to 0 0 after three clock pulses.
