Question

How the noise margin is reduced with pull up and pull down circuits?

Answer 1

Pullup - a network that provides a low resistance path to Vdd when output is logic '1' and provides a high resistance to Vdd otherwise.

Pulldown - a network that provides a low resistance path to Gnd when output is logic '0' and provides a high resistance to Gnd otherwise.

Answer 2

hay!!

PULLUP-

___________________________________

a network that provides a law resistance path to vvd when out put is a logic '1'


PULLDOWN-

__________________________________


a network that provides a law resistance path
to gnd when output is a logic 'o'




I hope it's help you
