Marquez, CpE, MSCS 2/7/11 Lecture Objectives After this lecture, students should be able to: familiarized with the different types of logic circuits, differentiate combinational and sequential logic circuits, know the different types of sequential logic circuits, familiarized with the different types of flip-flops, identify the different clock triggering mechanism of flip-flops, draw the equivalent timing diagram of clocked flip- flops, and 2/7/11 Topics Covered { 5 D 5 4 A 4 7 F -0 D 5 D -4 8 E 1 -B F B 1 -4 7 8 5 1 2 E C 9 5 F 8 } 1 { C 4 D 0 7 F 6 1 -4 9 7 C -4 2 6-9 3 F 0 -F 0 E D 8 2 5 D 4 F 8 6 } 2 { A 0 2 0 9 C 7 3 -2 6 0 7 -4 F E 0 -9 C 3 9 -E B 0 F B 0 B 6 E 7 8 B } Types of sequential logic circuits { D B 2 7 B C E A -D F 9 E -4 7 4 C -9 4 5 8 -A 8 7 4 A C A B 8 1 5 3 } 3 chronous sequential logic circuits) { 1 C 7 B D 4 3 -1 A 4 C -4 2 3 7 -9 A C F -4 F 6 3 D 1 2 E F B 6 B } 4 sic flip-flops { 0 B D B D A 9 E -A 9 4 D -4 8 E B -9 2 A B -8 6 1 D B 2 1 F 7 0 A 3 } 5 ked flip-flops { 0 F F B 6 9 F -C 2 3 E -4 6 8 7 -B 7 2 C -E 7 F 3 1 6 8 2 6 F 0 3 } 6 { 1 7 E F 8 D C A -3 C 2 D -4 8 9 6 -B A 9 C -4 7 0 1 3 B 5 0 2 1 } Timing parameters { C 1 C E A D F -3 D A 7 -4 0 C 9 -A 7 C 0 -0 5 F B 1 A D E 3 3 } ction to sequential logic circuits 2/7/11 Introduction Sequential Logic Circuit Digital circuits considered thus far have been combinational, i.e., the output at any instant of time are entirely dependent upon the inputs present at that time . Although every digital system is likely to have combinational circuits , most systems encountered in practice also include memory elements , which require that the system be described in terms of sequential logic . 2/7/11 Logic Circuits Known as the digital electronic circuit . Digital Electronic Circuit These are circuits that employed in the systems such as digital computers , electronic calculators , digital control devices , digital communication equipment , and other applications that are required in electronic digital hardware . Sequential Logic Circuit Sequential Logic Circuit 2/7/11 Combinational Logic Circuit It consists of logic gates whose outputs at any time are determined from the present combination of inputs without considering previous inputs....
