Question

Consider a GATE which outputs high voltage when all inputs are high and outputs low otherwise. How does this gate behave in positive logic gate and negative logic gate?

Answer 1

when all inputs are high then output is high and remaining all cases low is exact behaviour of AND gate.

how to know behaviour of one expression( actually depends upon gates ) in opposite logic ( either positive or negative )  is just do the DUAL of the expression.

accroding to above information, your requird answer is OR gate

Comments

So does that mean we just need to find out what is the positive logic gate doing and the negative logic gate will always be the dual of the postive logic gate??
