るＲＦ信号分配回路。[Scope of claim for utility model registration] RF that outputs RF signals to television receivers, etc.
In a VTR etc. with a built-in signal distribution circuit, when the VTR etc. is put into "recording" mode, the first switch is switched to the second position, the RF signal input is connected to the distributor connected to the second position, and the RF signal input is connected to the distributor connected to the second position. The same RF signal is divided into two parts by a divider, and the first R is divided into two parts.
The F signal is coupled to a tuner built in the VTR, and the second RF signal to be divided into two is coupled to a second RF signal.
When the switch is set to the second position and the VTR is set to the "playback" mode, the same VT is output.
An RF signal obtained by modulating the R playback signal by an RF modulator is output by switching the second switch to the third position, and when the VTR is not in a "recording" operation or a "playback" operation or when the power is off. When the R
An RF signal distribution circuit characterized in that it outputs an F signal input.
