A remotely-controlled signal receiving circuit of a system having a remotely-controlled transmission portion controlled by the output thereof has a microcomputer, a remote controller receiving portion, an inverting portion and a mixing portion for considering a signal received for a predetermined period after initiating the operation of the system, supplying an inverted noise signal sync with the noise signal as a noise elimination signal, mixing the noise signal with the noise elimination signal to check whether the mixed signal has a constant logic value or not, repeating the noise elimination signal outputting step or storing the noise elimination signal, and successively providing the noise elimination signal to eliminate the noise signal included to the remotely-controlled signal, thereby accurately controlling the system according to the remotely-controlled signal at any time.
