Karnaugh -Maps are useful for finding minimal implementation of Boolean expressions with only a few variables. However, they can be a bit tricky when “don’t cares” (X) are involved. By the K-maps below, perform the following tasks: a. Identify the minimal sum of products (MSP) expression. Show your groupings. b. Identify the minimal product of sum (MPS) expressions. Show your groupings. c. Are your solutions unique? If not, list and show the other minimal expressions. d. Is the MSP equivalent to the MPS?
