An information transmitting system including a transmitter and at least one receiver. The transmitter includes a modulator which is modulated by a first control signal intermittently, and whose center frequency is changed continuously in response to a second control signal. The receiver is provided with a frequency discriminator which demodulates the first and second control signals and the first control signal is applied as a first remotely controllable signal in digital fashion and the second control signal is applied as a second remotely controllable signal in analog fashion in the receiver.
