of course evryone knows about logic gates and, nor, nand + such like. if u dont, they are small curcuits usualy in chips, in short a number of inputs are fed into them (usualy 2) and e.g. with the and gate, if both inputs (1 AND 2) are at logic one then it will output at logic one. and with a not gate
(inverter) if the input is at logic 0 the output will be at 1 (if the input is NOT at 1) the out put will be at logic 1. and so on....... heres the cool bit..... introduce some real logic in there....... how about a SO gate, both inputs at 1 = gate goes SO and nothing is output, both inputs at 0 = gate goes SO and nothing is output, any variation in input = gate goes SO and nothing is output. then we could have a WHAT gate how ever many times the inputs are changed or repeated the WHAT gate does does not seem to notice. and a WHY gate that constantly questions the inputs. even better a GUTTED gate it somhow knows if your circuit is not working properly and outputs a logic 1 which lites a small L E D under the word GUTTED

Fuzzy Logic functionshttp://www.brunchin...ure-fuzzylogic.html A humor piece. Apparently, in attidiion to "true" and "false", fuzzy logic uses the values "sure", "whatever", "let's not talk about this right now", etc. [baf, Mar 29 2001]

There are 16 'functions' of two inputs, including trivial ones. There are 256 'functions' of three inputs, again including trivial ones.

Interesting challenge: design a device with the minimum number of inputs that can mimic any of the 16 possible two-input functions, with each of its inputs tied to one of the two input signals, VDD, or Vss.

//how about a SO gate, both inputs at 1 = gate goes SO and nothing is output, both inputs at 0 = gate goes SO and nothing is output, any variation in input = gate goes SO and nothing is output.//

Does the SO gate ever open?

Unless you mean a gate that has a truth table such that...
