Definition of "Propagation Delay" |
The amount of time for an output of an IC to change after an input was changed. Refer to IC Propagation Delay [design section of the site]. The time required for a shift in logic level to travel through one or more logic gates. Logic; The time between the specified reference points on the input and output voltage waveforms with the specified output changing from the defined level [diagram below]. The reference points on both the input and output waveforms are the same value which is midway between the maximum low-level input voltage (VIL max) and the minimum high-level input voltage (VIH min). / Propagation delay is the time required for a digital signal to travel from the input of a logic gate to the output. / A common carrier switching center in which trunks and/or loops are terminated and switched.In the DOD,common carrier is called commercial carrier. / (1) the delay between transmission and reception of a signal. Caused by the finite velocity of electromagnetic propagation. |
