Abstract

1,005,323. Multiplex systems; matching networks. STANDARD TELEPHONES & CABLES Ltd. March 23, 1964, No. 12141/64. Headings H3U and H4R. In an arrangement in which a number of filters F1 . . . Fn passing signals are connected to a common transmit amplifier C having a low input impedance, a resistor of value R is connected, as in Fig. 1, in series with each filter to match its output impedance. If the filters are of different characteristic impedance, matching may be obtained by the use of series and shunt resistors, as in Fig. 2.
