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 »
Design a decade counter using D-flipflop. Show all the steps involved 10m Dec2005 Decade counter A BCD counter follows a sequence of ten states and returns to 0 after the count of 9. These counters are also called decade counters. This type of counter is useful in display applications in which BCD is required for… Read More »
Explain the following with the help of a suitable diagram or an example:- Parameter passing using stack in 8086 assembly language 5m Dec2005 Most HLLs use the stack to pass parameters because this method is fairly efficient. To pass parameters on the stack, push them immediately before calling the subroutine. The subroutine then reads this data… Read More »
