Abstract

PURPOSE:To improve the reception during AM reception for a diversity receiving system in which the multipath noise caused during FM reception is avoided by switching plural antennas, by synthesizing the electric waves received through each of those antennas. CONSTITUTION:When an AM/FM changeover switch 7 is turned to the AM side, transistors TR4-TR6 are turned on with TR1-TR3 turned off, respectively. Thus the signal outputs to an output terminal 8 are all cut to make an FM reception impossible. The received signals through antennas A1-A3 are synthesizd through inductances L1-L3 plus capacitors C6-C8 to be applied to an AM receiving part through an output terminal 9.
