Explain the basic principle of Quine-McCluskey method of simplifying the Boolean expression with the help of an example function. 6m Jun2007

Explain the basic principle of Quine-McCluskey method of simplifying the Boolean expression with the help of an example function. 6m Jun2007 Quine McKluskey Method A tabular method was suggested to deal with the increasing number of variables known as Quine McKluskey Method. This method is suitable for programming and hence provides a tool for automating… Read More »

Design and draw a master-slave flip flop using JK flipflops. What are the advantages it offers over other flip flops? 10m Jun2007

Design and draw a master-slave flip flop using JK flipflops. What are the advantages it offers over other flip flops? 10m Jun2007 Master Slave Flip Flop Master-slave flip flop consists of two flip-flops. One is the master flip-flop & other is called the slave flip-flop. The figure shows implementation of master-slave flipflop using J-K flip-flop.… Read More »

List all the features of the RISC architecture. 6m Jun2015

List all the features of the RISC architecture. 6m Jun2007   List some important features of RISC architecture :  One instruction per cycle: A machine cycle is the time taken to fetch two operands from registers, perform the ALU operation on them and store the result in a register. Thus, RISC instruction execution takes about… Read More »

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 »
