Homework Statement
I have a weird boolean algebra expression for which I need to build a circuit using solely the NAND gates. There are 4 inputs A,B,C,D. From the truth table (I do not know how else to approach this question other than constructing the truth table and then trying to fit the output by playing around with gates) it seems that the output is zero unless C and D are both 1's or A and B are both 1's or more than two variables are 1's
Homework Equations
The Attempt at a Solution
Built the truth table. Aside from looking for tips to solve this, I am also looking to find out if there is some general method or rule of approaching these things.
