Claims (1)
て優先号機の故障検出をするだけでなく、放送開
始時に予備側の故障検出をする事を特徴とした故
障検出回路。 This failure detection circuit is characterized in that in a TV relay broadcasting machine having a No. 1 system and a No. 2 system, it not only detects a failure in the priority unit, but also detects a failure in the standby side at the time of starting broadcasting.
