Design and draw a 3 x 8 decoder using NOT gates and AND gates and explain its working. 8m Jun2007

Decoder converts one type of coded information to another form. A decoder has ‘n’ inputs and an enable line (a sort of selection line) and 2n output lines. Let us see diagram of 3×8 decoder which decodes a 3 bit information and there is only one output line which gets the value 1 or in… Read More »

Simplify the following Boolean function in POS form using K-maps, also draw a logic diagram using only NAND gates 5m Dec2005

 Simplify the following boolean function in POS form using K-maps : F (A, B, C, D) = Σ (0, 2, 4, 5, 6, 8, 10, 13, 15) Also draw a logic diagram using only NAND gates.         5m Dec2005    K-Map for F is: Thus, the simplified equations for F (A, B, C, D) =… Read More »
