본 고안은 PAL 방송방식의 음성다중 수신장치에 관한 것으로. 특히 PAL-B/G, PAL-1, PAL-D/K 방식의 음성신호를 모두 수신할 수 있는 PAL 방송방식의 음성다중 수신장치에 관한 것이다.The present invention relates to a PAL broadcast multiple voice receiver. In particular, the present invention relates to a PAL broadcast type voice multiple receiver capable of receiving all PAL-B / G, PAL-1, and PAL-D / K voice signals.

일반적으로 PAL 방송방식에서는 PAL-B/G, PAL-1, PAL-D/K 방식이 각각 있으며 각 방식은 음성중간주파수 신호가 영상중간 주파수 신호에서 5.5MHZ, 6.0MHZ, 6.5MHZ 간격으로 떨어져 있으므로 어느한 방식에 세트되어 있는 수신장치로는 하나의 방식만 수신할 수 있었다.In general, PAL broadcasting system has PAL-B / G, PAL-1, PAL-D / K system, and in each system, voice middle frequency signal is separated by 5.5MHZ, 6.0MHZ, 6.5MHZ interval from video middle frequency signal. Only one method could be received by the receiver set in one method.

즉 제2도에서 안테나에 입력된 신호는 RF 콘버터1)를 통해서 튜너(2)에 가해지고 튜너(2)에서는 어떤 채널이 입력되어도 일정한 중간주파수를 내보낸다. 상기 중간주파수는 다시 쏘(SAW) 필터(3)에 의해서 인접영상반송파 또는 인접음성 반송파의 세력을 제거한 후에 튜너 집적소자(4))에 인가되고 3단 증폭되어 진다. 증폭된 복합영상신호는 음성반송파 대역 저지필터(5)에 의해 순수한 영상신호만 증폭기(6)에서 증폭되어 영상출력되며, 음성반송파 대역 통과 필터(7)에 의해 음성반송파만 필터링되고 다시 튜너 집적소자(4)에 입력되어 3단증폭된후 음성출력된다.That is, the signal input to the antenna in FIG. 2 is applied to the tuner 2 through the RF converter 1, and the tuner 2 emits a constant intermediate frequency regardless of which channel is input. The intermediate frequency is applied to the tuner integrated device 4 and amplified by three stages after the SAW filter 3 removes the forces of the adjacent image carriers or the adjacent voice carriers. The amplified composite video signal is amplified by the audio carrier band stop filter 5 and only the pure video signal is output from the amplifier 6, and the audio carrier is filtered by the audio carrier band pass filter 7 and the tuner integrated device is again. It is input to (4) and amplified by three stages, and then the audio is output.

따라서 상기 음성반송파 대역 저지 필터(5) 및 대역통과필터(7)가 하나의 방송방식에 세트되어 있기 때문에 다른 방송방식의 음성신호는 수신할 수 없었다.Therefore, since the voice carrier band rejection filter 5 and the band pass filter 7 are set in one broadcast method, the voice signal of the other broadcast method cannot be received.

본 고안의 목적은 상기와 같은 종래 기술의 문제점을 극복하기 이하여 간단한 회로를 추가하여 PAL-B/G, 1, D.K 방식을 모두 수신할 수 있는 PAL 방송방식의 음성다중 수신 장치률 제공함에 있다.It is an object of the present invention to provide a PAL broadcast multiple voice rate device capable of receiving all PAL-B / G, 1, and DK schemes by adding a simple circuit to overcome the problems of the prior art as described above. .

상기 목적을 달성하기 위하여 본 고안은 튜너 집적소자에서 출력되는 복합영상 신호를 음성반송파 대역 저지필터를 거쳐서 순수한 영상신호만 증폭기에서 증폭하여 영상출력하며, 음성반송파 대역통과 필터를 거쳐서 필터링된 음성반송파를 상기 튜너 집적소자에서 3단 증폭하여 음성출력하는 PAL 방송방기 수신장치에 있어서,상기 음성반송파 대역 저지 필터는 주파수 f1, f2, f3의 각 음성반송파 대역 저지 필터를 병렬 연결하여서 구성하며, 상기 음성반송파 대역 통과 필터는 증폭기, 병렬 연결된 주파수 f1, f2, f3의 각 음성반송파 대역 통과 필터, △f2= f3- f1차주파수 발진기 및 △f2= f3- f2차주파수 발전기가 접속되어 상기 f1, f2, f3, 음성반송파와 △f1, f2발진신호를 혼합하는 혼합기, f3주파수 대역 통과 필터를 구비하여서 구성한 것을 특징으로 한다.In order to achieve the above object, the present invention amplifies only the pure video signal from the amplifier through the audio carrier band stop filter and outputs the video signal through the voice carrier band pass filter. In the PAL broadcast receiving apparatus for amplifying and outputting three-stage voices in the tuner integrated device, The voice carrier band rejection filter is configured by connecting each voice carrier band rejection filter of frequencies f 1 , f 2 , and f 3 in parallel, the sound carrier bandpass filter amplifier, connected in parallel frequencies f 1, f 2, each sound carrier bandpass filter f 3, △ f 2 = f 3 - f 1 primary frequency oscillator and △ f 2 = f 3 - f 2 A mixer is provided having a differential frequency generator connected thereto and mixing the f 1 , f 2 , f 3 , voice carrier and Δf 1 , f 2 oscillation signals, and a f 3 frequency band pass filter. It is characterized by one.

첨부된 도면을 참조하여 본 고안을 보다 상세하게 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

제1도에서 안테나가 연결된 RF 콘버터(1), 튜너(2), 쏘(SAW)필터(3), 튜너집적 소자(4), 병렬 연결된 5.5MHZ 저지필터(5A), 6.0MHZ 저지필터(5B) 6.5MHZ 저지필터(5C), 중폭기(6)를 차례로 연결하고, 상기튜너 집적소자(4)의 출력단에는 증폭기(7A), 병렬 연결된 5.5MHZ 통과 필터(7B),6.0MHZ 통과 필터(7C),6.5MHZ 통과 필터(7D), 홈합기(7E),6.5MHZ 통고 필터를 차례로 연결하며, 상기 혼합기(7E)에는 500KHZ발진기(7F), 1MIHZ 발진기(7G)를 연결하여서 된 것이다.RF converter (1), tuner (2), saw (SAW) filter (3), tuner integrated element (4), 5.5MHZ rejection filter (5A) connected in parallel, 6.0MHZ rejection filter (5B) in FIG. ) 6.5MHZ stop filter (5C), the heavy amplifier (6) is connected in order, and the output terminal of the tuner integrated device (4) amplifier 7A, parallel 5.5MHZ pass filter (7B), 6.0MHZ pass filter (7C) ), 6.5MHZ pass filter (7D), groove mixer (7E), 6.5MHZ notification filter is connected in order, the mixer (7E) is to connect the 500KHZ oscillator (7F), 1MIHZ oscillator (7G).

이와 같이 구성된 본 고안의 작용 및 효과를 다음과 같다.The operation and effects of the present invention configured as described above are as follows.

튜너 집속소자(4)에서 3단 증폭된 복합영상 신호는 B/G,1, D/K의 어떤 신호이던지 대역 저지 필터(5A)(5B)(5C)에 의해 음성중간 주파수는 삭제되고 순수한 영상신호만이 증폭기(6)에서 증폭되어서 영상출력된다. 또한 증폭기(7A)에서 증폭된 복합영상 신호는 대역 통과 필터(7B)(7C)(7D)에 의해 B/G, I, D/K의 중의 한 신호가 필터링 되어져 혼합기(7E)에 인가되고 발진신호 △f1= 1MHZ, △f2=500KHZ와 혼합된다.The composite video signal amplified by the tuner focusing element 3 is any signal of B / G, 1, D / K. The band-stop filter 5A, 5B, and 5C removes the audio intermediate frequency and produces a pure video. Only the signal is amplified by the amplifier 6 and outputted as an image. In addition, the composite video signal amplified by the amplifier 7A is filtered by one of B / G, I, and D / K by a band pass filter 7B, 7C, and 7D, and applied to the mixer 7E and oscillated. Mixed with signals Δf 1 = 1MHZ, Δf 2 = 500KHZ.

예컨데, B,/G 방식 신호일때는 1MHZ에 의해 혼합되어져 주파수 천이된 6.5MHZ 성분이 6.5MHZ 대역통과필터(7H)에서 필터링 되어 튜너 집적소자(4)에 재입력되고 3단 증폭되어 음성 출력된다. 예컨데 1방식신호일때는 500KHZ에 의해 혼합되고 주파수 천이된 6.5MHZ 성분만이 튜너 집적소자(4)에 인가된다.For example, in the case of the B // G signal, the 6.5MHZ component mixed by 1MHZ and frequency shifted is filtered by the 6.5MHZ bandpass filter 7H, re-input to the tuner integrated device 4, and amplified by three stages. For example, in the case of a one-way signal, only 6.5 MHZ components mixed and frequency shifted by 500 KHZ are applied to the tuner integrated device 4.

이상과 같이 PAL 방식의 B/G, I, D/K 방식의 어떤 신호가 입력되더라도 최종 출력단자에서 D/K 방식의 6.5MHZ로 출력되므로 음성다중 수신이 가능하게 된다.As described above, even if any signal of PAL B / G, I, D / K type is input, 6.5 MHZ of D / K type is output from the final output terminal, thereby enabling multiple voice reception.

따라서, 하나의 수신기로 여러방식의 방송방식을 모두 수신할 수 있는 잇점이 있다.Therefore, there is an advantage in that it is possible to receive all kinds of broadcasting methods with one receiver.
