Hi! there, Guys I have just started doing boolean expressions and Iam really stuck with my assignment which in three days. Any help would be appreciated greatly. I know all about the rules and regulations but Iam really in a fix. Please help. The question is: Write the following boolean expression in sum-of-minterms form: F(A,B,C) = A. At least this will get me started.
Hello, Some links on boolean algebra can be found in the links of this page of the EDUCYPEDIA. http://www.educypedia.be/electronics/digitallogic.htm Greetings, Bertus
mate this is basic stuff, you should know this!!! basically you should start with a truth table for F(A,B,C) = A , which means where A is high (1), your out put is high. min terms 0 0 0 = 0 = m0 0 0 1 = 0 = m1 0 1 0 = 0 = m2 0 1 1 = 0 = m3 1 0 0 = 1 = m4 1 0 1 = 1 = m5 1 1 0 = 1 = m6 1 1 1 = 1 = m7 therefore your sum of min-terms would be F(A,B,C) = ∑m(4,5,6,7) this then leads on to, Standard Sum of Products (SSOP) SSOP = AB'C' + AB'C + ABC' + ABC make sure you learn how to get from SSOP to SOP, SPOS and POS. these will most likely be asked in an exam.
hi,,, u see that expression fix in A so u add A in all minterms and the rest varaible u alternate between their values so the minterms 4,5,6,7 and note that A appears uncomplemented
gilbertkunda, You really ought to download the program found in this link. http://forum.allaboutcircuits.com/showthread.php?t=22347 . It will give you the minterms of just about any Boolean expression in a flash. Maxterms also. Make sure you read the short documentation and set the program for the right number of logic variables. Although you cannot bring this program into a test, it is a great educational help because it allows you to check your work on practice problems. Ratch
0^1=0 0^0=0 0U1=1 0U0=0 1^1=1 1U1=1 This is boolean math question, another expression is ture and fause. You should be learn it up.
