Hello, I had to do complete the problems as outlined below this paragraph. I completed parts a-b as per the attached image, however I cannot complete part c which is 'how to use De Morgan's theorem to prove a relationship between the two Karnaugh map simplified formulas'. Can anyone see what I am doing wrong here ?
Thanks kindly for any help.
(a)
Design a circuit which has the four bits of a BCD number as its inputs and
has an output X so that:
X = 0 if inputs are a valid BCD number
X = 1 if inputs are an invalid BCD number.
(b)
Redesign the circuit of (a) so that:
X = 1 for valid BCD
X = 0 for invalid BCD.
(Note: DO NOT just invert your input (a).)
(c)
Use de Morgan’s theorem to prove that the Boolean Algebra expressions
you obtained in (a) and (b) are the inverse of each other.
