Abstract

PURPOSE:To increase the reliability with a simple constitution, by mixing the output from an oscillator separately provided with a signal obtained from a lead filter and modulating and transmitting the mixture at the same time. CONSTITUTION:The output of an oscillation circuit 4 using a lead filter is mixed with the output of an oscillator 6 with the mixing circuit 5. Further, this mixed output is modulated with the output of a high frequency oscillation circuit 1 with a modulation circuit 2 and transmitted with a transmission circuit 3. On the other hand, the signal received at the receiver is fed to two filter circuits. Further, the signal in frequency corresponding to the output of the circuit 4 and the oscillator 6 is picked up at the same time. Further, the signals appear at the same time, then the drive circuit is driven.
