What is the difference between master-slave flip-flop and edge flip-flop?

The difference between master-slave flip-flop and edge flip-flop: 1. The triggering conditions are different. The master-slave flip-flop is triggered by the falling edge, while the edge flip-flop is triggered by the rising edge; 2. The action characteristics are different; 3. CP The number is different, the master-slave flip-flop has 2 gate signals, while the edge flip-flop only has 1 gate signal.

What is the difference between master-slave flip-flop and edge flip-flop?

The difference between the master-slave flip-flop and the edge of the digital circuit is: different trigger conditions, different action characteristics, and different number of CPs.

1. Different trigger situations

1. Master-slave trigger: falling edge trigger

2. Edge trigger: rising edge trigger

2. Different action characteristics

1. Master-slave flip-flop: During the high level or low level of cp, the input signal first determines the state of the master flip-flop; when the falling edge or rising edge of cp arrives, the state of the master flip-flop remains unchanged Transferred to the slave trigger, showing the status of the entire trigger. The state transferred to the past depends on all inputs during the high or low level of cp.

2. Edge trigger: It only depends on the input at the moment when the cp edge arrives.

3. Different CP numbers

1. Master-slave trigger: There are 2 gate control signals (CP)

2. Edge trigger: only 1 gate control signal (CP)
