CHAPTER 18

Sequential Circuits: Flip-flops and Counters

LEARNING OBJECTIVES

After reading this chapter, you will be able to:

  • Appreciate the difference between combinational and sequential circuits; and the difference between synchronous and asynchronous sequential circuits
  • Understand the principle of working of various types of flip-flops, both un-clocked and clocked, with the help of truth tables and timing diagrams
  • Understand the problem of racing in flip-flops and the method to overcome this problem using a master–slave JK flip-flop
  • Understand the principle of working of various types of counters, both synchronous and asynchronous
  • Design counters to meet the required specifications
