Introduction to sequential networks

The transition from combinational to sequential networks is explained step by step, starting from a simple gate with feedback and arriving to the structure and behavior of the principal types of flip-flops. They are classified according to their temporal response (direct command, level enabled, master–slave, and edge triggered) and the logical operation (SR, D, JK). The timing parameters of physically implemented devices are considered. The chapter introduces the concept and techniques for synchronization that will be further examined in the following ones.
