Propagation Delay
In digital logic, every gate has got some finite amount of delay because of which the
change in the output is not instantaneous to the change in the input.
In simple terms, the times it takes for an input to appear at the output is called the
propagation delay.
In Figure 6, tPHL, describes the time it takes for an input to cause the output to change
from logic-level-high to logic-level-low.
Similarly, tPLH, refers to the delay associated when an input change causes the output to
change from logic-level-low to logic-level-high.
The overall delay is average of these two delays.

What is retention flip flop?
Flip flops , which retain there data even after in power down mode, are referred as retention flip flops.
What are the different types of Flip-Flops. Draw the symbol and present characteristic table for each type.?
I want to know about those flip-flops that are maked by joining other flip flops.
What are the disadvantages of flip flops?
The primary disadvantages of flip flop is their reacting time between the input signal and resultant Output if the signal changes between this reaction time the flip flop is unable to identify....... another disadvantage is that their is a Race between the flip flops when connected togather to change their stages
What is the Use of clock in flip flops?
The primary use of a clock in flip flops is to provide the trigger pulse to the flip flop
How many flip-flops are required for a counter that will count from 0 to 511?
It takes nine flip flops to count from 0 to 511.
What limits the maximum counting speed of a ripple counter?
The maximum counting speed of a ripple counter is limited by the propagation delay of the flip-flops used in the counter circuit. As the count propagates through each flip-flop in series, there is a cumulative delay that increases with each stage. This limits the speed at which the counter can reliably count without errors.
Do asynchronous counters have any advantages?
Yes, asynchronous counters have several advantages, including simplicity and reduced component count, which can lead to smaller circuit designs. They require fewer flip-flops since not all flip-flops are clocked simultaneously, making them easier to implement in certain applications. Additionally, asynchronous counters can operate at higher speeds for certain designs, as they do not have the delay associated with clock propagation through all flip-flops. However, they may suffer from timing issues and glitches, which can be a drawback in more complex applications.

Why does the procedure produce a glitch in Asynchronous Counters?
Asynchronous counters, often referred to as ripple counters, can produce glitches due to the propagation delay inherent in their design. When a flip-flop changes state, it may take a brief moment for this change to propagate to subsequent flip-flops, leading to a situation where not all flip-flops update simultaneously. This can create temporary incorrect outputs, or glitches, as the counter transitions between states. The cumulative effect of these delays can result in unintended counts or erroneous states during transitions.
Who made flip flops?
Modern day flip flops were made by the Japanese and became popular after World War ll. The soldiers brought the flip flops back with them. In ancient times, the Egyptians wore sandals that looked like flip flops.
Where do flip flops originate from?
Flip-Flops most definatley originate from china as that is where everthing comes from
Can you wear flip flops every day?
i believe that you can wear flip flops everyday. personally i do
If you have no toes can you still wear flip flops?
No, because flip flops are held on using the toes.
Is it illegal to drive in flip flops in Louisiana?
Yes, it is illegal to drive in flip flops in Louisiana.
What do you do with the flip flops on Wimpy Boardwalk in poptropica?
you use the flip flops to collect the flying disc
Are flip flops magnets?
It's possible there may be some company producing a magnetic product they call "flip flops" and/or flip flop sandals that are magnetic, either miniature or full, wearable sized; but, no, flip flops are not magnets, generally speaking. Flip flops are a simple type of sandal.
How delay occur in 4017 decade counter?
Delay in a 4017 decade counter occurs mainly due to the propagation delay of the internal flip-flops and logic gates used in the circuit. When a clock pulse is applied, it takes a finite amount of time for the changes in output states to propagate through the circuit, leading to a delay in the output transitions. This delay can affect the timing of subsequent circuits connected to the counter. Additionally, external factors like load capacitance and temperature can also influence the overall delay.
