3/30/2024 0 Comments D rising edge triggered flip flopHowever, a flip-flop will be used as part of the circuits in chapter 10. So this chapter will not implement a flip-flop. This is illustrated in Figure \(\PageIndex\): Actual implementation of a D flip-flopÄue to a problem known as debouncing, it is hard to illustrate a flip-flop in isolation as a circuit. The concept behind a flip-flop is that current flowing within a circuit is not instantaneous, but always has a short delay depending on the size of the circuit, the gates that it must traverse, etc. All flip-flops in this text will be positive edge trigger. The flip-flop can be triggered by a raising edge (0->1, or positive edge trigger) or falling edge (1->0, or negative edge trigger). It is said to trigger on the edge of the clock pulse, and thus is called an edge-triggered flip-flop. An edge triggered flip-flop (or just flip-flop in this text) is a modification to the latch which allows the state to only change during a small period of time when the clock pulse is changing from 0 to 1. flip-flop depending on the inputs one is carried out at either the rising edge of the clock pulse or the falling edge.
