Title: Switching signal transmission system
Inventor: ITO TOSHIKI
IPC: H04B1/74
Filed: 1990-10-08
Abstract: PURPOSE:To facilitate th transmission of a switching signal by frequency- dividing a received signal and detecting the presence of a DC component so as to decide whether or not the signal is angular-modulated. CONSTITUTION:A signal inputted from an indoor section is branched at an outdoor section and the signal is inputted to a frequency divider circuits 5, 6. In the normal operating state where angular modulation is implemented by a data signal, a DC component is generated resulting from frequency division by a proper stage numbers. Conversely, when the signal is non-modulated, no Dc component is generated. Thus, DC detection circuits 7, 8 separate the Dc component from the frequency division output and DC decision circuits 9, 10 apply comparison with a setting voltage after integration for a prescribed time so as to discriminate at which system of modulation stop circuits 1, 2 is decided. A control circuit 11 uses a decision result and outputs a switching signal of an active and standby system only when the result of the both is logically matched.
