Abstract

PURPOSE:To increase the separation between both the cannels, by rejecting the specific band of both the channel signals in transmission and superimposing the identifying signal only to one channel signal. CONSTITUTION:The reproducing signal from the tape decks 301, 302 sent from the personnel requesting the confirmation is respectively amplified, and the part 100Hz or lower is cut off through HPFs 321, 322, and after amplification, it is recorded in the decks 341, 342. In this case, the reproducing signal of the tape deck 302 is branched to pick up the synchronizing signal and the synthesizer 44 is provided between HPF 322 and the amplifier 332, and the output of the oscillation source of three waves f1-f3 100Hz or less is coded through the switches 411-413, and synthesis is made through BPC421-423 corresponding to the frequencies f1-f3 to add the digital signal representing the content of broadcast to the reproducing signal from the tape deck 302.
