A logic circuit is shown in the diagram....

A logic circuit is shown in the diagram. Draw the output signal at the point X and Y for the input signal shown in the figure at point A.

Text Solution

Verified by Experts

Here, the output of the NOT gate will be equal to `X=barA`. Hence the output obtained will be equal to opposite of A. This signal is given as input to another NOT gate. The signal again gets inverted. As a result we again get back the original signal A. `(Y=barX=barbarA=A)`
