Question

difference between positive and negative edge triggered flip flop

Answer 1

positive edge triggering- when a flip flop is required to respond at a low to high transition state is known as positive edge triggering

negative edge triggering-when a flip flop is required to respond at a high to low transition state is known as negative edge triggering

Answer 2

The difference between positive and negative edge triggered are as follows:

• A positive edge is the low-to-high transition. A negative edge is a high-to-low transition.
• Positive edge flip-flops will allow its outputs to change its inputs only at the positive spikes. The negative edge only responds to the negative-going edge of the clock.
• Positive edge-triggered flip flop sample data on the rising edge of the clock. Whereas, negative edge sample data on the falling edge of the clock.
