专利汇可以提供Interference wave detecting system专利检索,专利查询,专利分析的服务。并且PURPOSE:To prevent automatically interference by detecting the generation of interference from the reception output of a radio receiver. CONSTITUTION:The output signal of a busy detection circuit 13 transmits logical 1 when a voice during talking exists. A clear input CL signal is fed to a flip-flop 5 during this time and its operation is inhibited. Then the output of an inverting circuit 14 goes to ''0'' and no output appears at AND circuit 6, 15. When a busy tone is intermitted, the output of a detection circuit 13 goes to ''0'', the flip- flop 5 and the AND circuit 6 start operation, a clock signal appears at the output of the AND circuit 15, the signal is counted and counters 8, 10 to which a count-up signal is outputted is cleared. After a time T from the clearing of the counter 8, the talking is started again and a signal of the busy detection circuit 12 is transmitted, then the operation of the flip-flop 5 and the AND circuit 6 is inhibited.,下面是Interference wave detecting system专利的具体信息内容。
