PURPOSE: To provide the subject system wherein the period of continuous pulse rows and pulse occupying ratio are varied by transmitted information, thereby transmit simultaneously two kinds of information and also transmit a large quantity of information pieces in a short period of time. CONSTITUTION: A continuous pulse row 1 has a period of T and a pulse width of t, and the period T of the pulse row 1 is varied by information signal from the terminal 2a in a transmitter 2, and the pulse occupying ratio d = t/T is varied by input information of the terminal 2b. The modulated pulse is supplied to a receiver 3 through a transmission line 4, and by the calculation of the sampling pulse the period of the received pulse the period of the received pulse and the pulse width are obtained, and the pulse occupying ratio is obtained by the ratio of respective caluclate values to restore information to the original state.
