Title:
REMOTE CONTROLLER
Document Type and Number:
Japanese Patent JPS5750013
Kind Code:
A
Abstract:
PURPOSE:To operate a target equipment selectively without malfunction by detecting and converting a transmitted frequency signal into a digital value and by detecting coincidence with a set value of a reception side. CONSTITUTION:A signal received by a receiving antenna 9 is sent to an FM detector 14 through a high-frequency amplifying circuit 10, frequency converting circuits 11 and 12, and an intermediate frequency amplifier 14. The signal detected by the FM detector 14 is sent to a waveform shaping digital filter 15 and also supplied to a data discriminator 16. The data discriminator 16 receives a command from an (n)-bit address setting part 17 at a reception side as well and, only when it coincides with the input signal, generates a coincidence signal 18. The coincidence signal is sent to a logic sequence relay driver 21 through a signal switching circuit 20 to operate a controlled object 22.
