Boolean Algebra and Logic Simplification - Technical MCQs

Q1:

Which is the correct logic function for this PAL diagram?

A

B

C

D

ANS:C -

As PAL has programmable AND followed by fixed OR gates. The first AND gate has inputs as INVERTED B and uncomplemented A. Also the second AND gate has similarly INVERTED A and uncomplemented B as their inputs. Finally the outputs of and gates will be ored together leads to the output of X-OR GATE. (option C).
