Abstract :
To eliminate interference in telephotograph transmission through broad-band carrier equipment, it was decided to cancel it from the signal delivered by the carrier facility instead of modifying the carrier equipment. Consequently, a recently developed telephotograph level compensator, consisting of a pilot channel arrangement designed for insertion in the telephotograph connecting circuits, is utilized.
