Homework Statement
Find the minimum Sum-Of-Product Expression for:
f = ab'c' + abd + ab'cd'
The Attempt at a Solution
By introducing the missing variable in term 1 and term 2 I can get an expression that has all the variables: a, b, c, and d.
I do so by:
f = ab'c'd + ab'c'd' + abcd + abc'd + ab'cd'
I can combine terms like so: (1 & 2),( 2 & 5), (3 & 4) I get:
f = ab'c' + ab'd' + abd
This hardly seems minimized from the original expression. Thanks for any help.
