Abstract

In a method for controlling transmission band, minimum intervals are provided for a plurality of signal sources, respectively, so that each of the signal sources turns into a condition where a signal can be transmitted therefrom when the minimum interval thereof is elapsed. The minimum interval for each of the signal sources is counted since the last signal is transmitted therefrom. A waiting time for each of the signal sources is counted since the minimum interval thereof is elapsed. One signal source is selected from the signal sources whose waiting time is the longest so that the selected signal source transmits a signal to the common transmission line. The minimum interval and the waiting time for the selected signal source are renewed in accordance with the time-slot interval and the waiting time thereof.
