ABSTRACT:
In a signal distribution system, a bus transmission path is provided on which at least one terminal of a pair of transmission lines terminates in a proper potential through a line-to-ground characteristic impedance Z.sub.0. A pair of differential output terminals of at least one transmission circuit are connected to the corresponding pair of transmission lines on the bus transmission path to deliver differential transmission signals of a fundamental frequency f as output signals. A pair of differential input terminals of a respective one of a maximal number of reception circuits, N, are connected to the corresponding pair of transmission lines through a corresponding pair of branch resistors. The input terminal of the respective reception circuit has a characteristic of an input impedance Z.sub.L given below:
