Abstract

966,044. Diversity reception systems. NIPPON ELECTRIC CO. Ltd. May 12, 1961 [May 16, 1960], No. 17487/61. Heading H4L. In a diversity reception system the received signals after detection are supplied to the respective control grids of valves 1 and 2. A high resistance 3 in the common cathode circuit is shunted by a high-pass filter 8 which passes the signal frequencies, the resistor 3 by degenerative feedback reducing the unwanted noise components in the output circuit. The combined output signal is taken from a transformer 9 in the common anode circuit. The circuit is stated to be an improvement on a known circuit in which the signals are combined in the common cathode circuit of a pair of valves.
