Definitions for "Propagation Delay"
Time interval between specified reference points on the input and output voltage waveforms.
The period between when a signal is placed on a circuit and when it is recognized and acknowledged at the other end. Propagation delay is of high importance in satellite channels because of the great distances involved.
One of the test parameters used when testing Category 5E or Category 6 UTP, FTP or ScTP Permanent Links or channels. Propagation delay measures the time taken for the signal to travel from the transmitter to the receiver.
