Help on Looser-Take-All / Winner-Take-All circuit

[Etantonio]

Good morning,
a friend of mine have inserted this post on a Forum I created on my site
www.etantonio.it/en , this is the question :

"Someone knows something about LTA/WTA circuits?
I mean the best approach to the problem,
the best topology and all that can be usefull
to design an accurate and high-speed LTA?"

I don't know the answer, if you know it please post it just following this link:

Many Thanks,

Start with an N-input AND or equivalent.
Each input is driven from the output of a 3-state logic circuit; state
1 = NOT VOTED, state 2 = YES, state 3 = NO; reset all to state 1 at
power up.
The 3-state logic is wired to prevent a voter from changing the vote
after voting; both state 2 and state 3 lock out any inputs.
I designed and built such a beast about 50 years ago using relays;
rather simple.

Alter above suggestion as requirements dictate.
