In NAND Gate the frequency is low only when there is high input. But when low or dissimilar frequency input entered the output is high frequency.

OR gate is also correct.. even i thought it could be the ans. but it isnt.. please justify...

OR gate also satisfy these conditions. So it can also b considered?

Accoring to OR gate if any one i/p is low it will be then high. Why don't you consider that ?

It is only NAND gate in which the output is high when one input is low.

According NAND gate principle if at lest any one of the input is low the output high.

NAND GATE=AND+NOT
our output is high when inputs are zero.
