Abstract

PURPOSE:To make it possible to miniaturize a discriminator without using any power supply, by receiving an external specific radio wave, by converting it into DC power and then by using the power as a power supply. CONSTITUTION:An external radio wave arrives at receiving antenna 1 and the electric vibration of only the radio wave is induced to tuning circuit 2. This power is sent to rectifying circuit 3, which obtains DC power, and this is used as a power supply to put oscillator 4 and modulating circuit 5 into operation. This modulating circuit 5 is designed to perform modulation into a predetermined signal, so that the fixed signal will be transmitted from transmitting antenna 6.
