The digital logic circuits are basic building blocks of the digital systems (digital computers). These digital logic circuits can be classified into two categories such as combinational logic circuits and sequential logic circuits.

Unit 71: Combinational and Sequential Logic Unit code: K/601/1362 QCF level: 4 Credit value: 15 вЂў Aim This unit aims to provide learners with the skills and understanding required to design and build electronic circuits that use combinational and sequential logic. вЂў Unit abstract This unit will develop learnersвЂ™ understanding of digital techniques and the practical applications of both Combinational Logic Circuits are made up from basic logic NAND, NOR or NOT gates that are вЂњcombinedвЂќ or connected together to produce more complicated switching circuits. These logic gates are the building blocks of combinational logic circuits. An example of a combinational circuit is a decoder, which converts the binary code data present at its input into a number of different output
