Abstract

PURPOSE:To transmit the content of fault to the place such as monitor room without injuring the essential functions such as broadcast at fault, by transmitting the phase of carrier signal with inversion or non-inversion depending on the information to be transmitted and by reproducing the pulse thru the detection of the phase at the reception side.
