Hi,

How will you construct a mod 5 counter using T flipflop?

Thanks
 

mod-5 counter

and the output of the first and the third FF output and use it as output and also to give reset signal to all the three FF....
 
modulo 5 counter

graciousparul,
A.Anand Srinivasan's suggestion is a good one. I would add one caution, however. In going from state 011 to 100, there is a potential race problem. If the 1st (LSB) stage is slower thatn the 3rd (MSB) stage, then there will be a momentary pulse from the and gate, causing the counter to reset after state 011. By placing a small delay (maybe as simple as an RC low pass filter) between the And gate output and the reset inputs, this "trash pulse" can be eliminated.
Regards,
Kral

Hi,

Just see the attachment, which describes about MOD 5 Counter by taking a good example (Digital Clock).
