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.
=>=0
Since is fed back to
,the counter resets to 0 0 after three clock pulses.
