ISRO | ISRO CS 2008 | Question 25
The logic operations of two combinational circuits in Figure-I and Figure-II are
(A) entirely different
Explanation: The Two functions are entirely different as:
Figure 1: The logic gates derive the following function:
F1 = ((X + Y')' + X)' = ((X + Y')')'. X' = (X + Y'). X' = XX' + X'Y' = X'Y'
Figure 2: It is simple AND gate which has 1 input already complimented.
F2 = XY'
So, these two functions are entirely different.
