I am getting confused with how to simplfy equations i have put an example below and simplified in two ways can anyone tell me if i am correct? Or where i have gone wrong ! = NOT & = AND !A&!B&!C + !B&C&!D + A&C + A&B !A&!B(C+!C) +!B&!D + A&C + A&B !A&!B + !B&!D + A&C + A&B Is this as far as I can go or can !A&!B + A&B Cancel out also leaving !B&!D + A&C Or is this correct way Method 2 !A&!B&!C + !B&C&!D + A&C + A&B !C(!A!B+AB)+!B&C&!D + A&B !B + C&!D + A if someone can clear this up that would be helpful Thanks
Kayne, You have gone wrong several ways. 1) You have used a clunky, clumsy notation. No one wants to read your equations that way. Try instead A'B'C' + B'CD' + AC + AB . 2) You have not searched this forum for an answer. Two days ago I answered a similar question. http://forum.allaboutcircuits.com/showthread.php?t=20992 3) You have not used a Karnaugh map (K-map). Try it, and you will like it. Ratch
The verilog notation is a matter of preference, without using TeX, getting the equation readable is difficult. Here is the TeX version, put the tex and /tex tags around it to make it look like the image below, which is auto-generated when you click Preview or Submit: \overline{A}\overline{B}\overline{C} + \overline{B}\overline{C}\overline{D} + AC + AB
