What does Signal Transition Speed refers to????

Question

ganeshie8 · Answer

It refers to time it takes for a signal to change from one logic level to another. in digital circuits, it is the time taken to charge/discharge the load capacitance via interconnect resistance..

Can these switching be relative to the speed to light?? I mean Any practical example of this..??

ganeshie8 · Answer

hey in which context you asked the Q ? If it is integrated circuits, it takes ~ 100 picosecond to travel 100 micron..

anonymous · Answer

I asked coz Prof. Anant Said if the speed id relative to the speed of light then we can't apply the LMD so i just wanted to know the practical example of any circuit in which we can not apply the Lumped Circuit Abstraction

If you are talking about a signal transitioning from an electric level to another, the transition TIME is usually the time it takes to go from 10% of the previous value to 90% of the final value; sometimes (as with op-amps) you can find a parameter named slew-rate that is expressed in V/s, i.e. how many Volts the signal change in a second.|dw:1339531652263:dw|
