Which of the following describes the operation of a positive edge-trig...
Operation of Positive Edge-Triggered D Flip-Flop
The positive edge-triggered D flip-flop is a type of sequential logic circuit that stores one bit of data. It has a single input called D (data) and two outputs called Q (output) and Q' (complementary output). The operation of the positive edge-triggered D flip-flop is as follows:
Leading Edge of the Clock
On the leading edge of the clock, the input D is sampled and stored in the flip-flop. The output Q reflects the value of the input D at the time of the leading edge of the clock. The output Q' is the complement of the output Q.
Trailing Edge of the Clock
On the trailing edge of the clock, the output Q remains stable and retains its previous value. The output Q' also remains stable and retains its previous complemented value.
Advantages of Positive Edge-Triggered D Flip-Flop
The positive edge-triggered D flip-flop has the following advantages:
- It is immune to glitches and noise on the input D during the clock transition.
- It has a predictable and reliable timing behavior.
- It can be easily cascaded to build more complex sequential circuits.
Conclusion
The positive edge-triggered D flip-flop is a fundamental building block of digital circuits. It provides a simple and reliable way to store one bit of data and synchronize it with a clock signal. Its operation on the leading and trailing edges of the clock makes it suitable for a wide range of applications, such as registers, counters, and state machines.

Which of the following describes the operation of a positive edge-trig...
Edge-triggered flip-flop means the device will change state during the rising or falling edge of the clock pulse. The main phenomenon of the D flip-flop is that the o/p will follow the i/p when the enable pin is HIGH.
