Question

Prepare the truth table for given logical diagrams. Write the expression for output and name the output function.

Answer 1

Hello Champ!!

Here the given logic gate is a Nand Gate with shorted input

And this Gate is equivalent to NOT gate.

For the output expression and truth table please do refer the attachment given :-

Answer 2

Given :same input NAND gate

input X

Y =( X.X)'

here ' represents not operation

X-----------X.X----------------Y(X.X)'

0---------- 0--------------------1
1-------------1--------------------0

OUTPUT OPERATIONS PERFORMED = NOT OPERATION
Y = X' (NOT X)

Explanation:

X : enters into both inputs

AND gate multiplies the inputs
ie

0.0 = 0

1.1 = 1

at the end there is a bubble,which performes NOT OPERATION

if we enters 0 it gives 1

and vice versa

so, finally we get 1 on entering 0 and 0 at entering 1,

So,NOT operation performed.
