For various systems it is necessary to measure the delay that signals will experience as they transverse various communications paths. The path may involve telephone h-&ted pairs, radio frequency transmission and reception, splitters, nonanalog transmission medium (ex. digitized analog facilities), etc. The delay measurement is usually performed as a loop back type of operation. Figure 1 is a typical example.
