The present invention relates to a multi-transmission method and a receiver of a high frequency signal and a low frequency audio signal for amplifying a signal so that simultaneous or selective viewing is possible.

일반적으로, 아파트단지나 집단수용가의 지역에서 텔레비젼수신용 공청안테나를 각 동마다 별개로 설치하고 있으므로 물품의 구입 및 설치작업이 복잡하며, 사용중에 불합리한 관리소홀로 인하여 설치상태가 불안정하여 고장율이 높아 보수작업이 뒤따르는 등의 비경제적인 결점이 있었다.In general, the TV receiving public antennas are separately installed in each apartment complex or group area, so the purchase and installation work is complicated, and the installation status is unstable due to unreasonable management during use. There was an uneconomical flaw such as the work that followed.

본 발명은 종래의 문제점을 감안하여 하나의 선로에 고주파와 저주파신호를 혼합하여 다중전송함으로서 회로 및 기계적 구성의 간소화와 설치작업의 용이함 때문에 경제적이며, 자동이득조절용 증폭기를 사용하여 수용가의 호수에 구애됨이 없이 고장율이 적은 고감도의 시청 효과를 얻을 수 있도록한 것이다.In view of the conventional problems, the present invention is economical due to the simplicity of circuit and mechanical configuration and ease of installation work by mixing and transmitting high frequency and low frequency signals in one line, and using the automatic gain control amplifier in the lake of the consumer. Without failing, high sensitivity viewing effect with low failure rate can be obtained.

본 발명은 공청안테나에서 출력된 고주파신호와 유선 방송기에서 출력된 저주파신호의 양신호는 혼합기에 의해 합성되고, 이 신호는 각 고주파증폭기를 통과하고, 이 증폭된 다중신호는 3분배기 및 2분배기로 분배하여된 다중 신호는 각 수신처에 설치된 다중분기수신기의 입력측에 입력되고, 이 다중신호중에서 저주파통과코일을 통과한 한쪽 저주파신호는 스피커와 결합되는 메칭트랜스에 유입되며, 또한 고주파통과콘덴서를 지난 고주파신호는 2분기기에 의해 별도의 고주파출력단자와 보조단자를 인출하여, TV용으로 사용하여서 상기 다중신호를 재생하며, 상기의 또다른 다중신호는 다음단 수신처의 다중분기수신기로 출력이 되어서 계속적으로 상호반복작용을 하도록 구성되어 있다.In the present invention, both signals of a high frequency signal output from a public antenna and a low frequency signal output from a cable broadcaster are synthesized by a mixer, and these signals pass through each high frequency amplifier, and the amplified multiple signals are distributed to a triple divider and a divider. The multiplexed signal is input to the input side of the multi-branch receiver installed at each receiver, and one of the multiplexed low-frequency signals that pass through the low-frequency pass coil flows into the matching transformer combined with the speaker, and the high-frequency signal past the high-frequency pass capacitor. Withdraws the separate high frequency output terminal and the auxiliary terminal by the second branch, and reproduces the multiple signal using for TV, another multiple signal is output to the multi-branch receiver of the next destination continuously It is configured to repeat.

이와 같은 본 발명의 첨부도면에 의하여 작용효과를 상세히 설명한다.By the accompanying drawings of the present invention will be described in detail the effect.

제 1 도에 도시한 바와 같이 각 신호를 혼합하여 전송하는 계통도에서 유선방송기(1)를 동작하여 출력된 저주파음성신호(AFC)와, UHF안테나(3)와, VHF하이채널안테나(4)와, VHF로우채널안테나(5)를 연결하고, VHF하이로우혼합기(6)와, UHF-VHF 혼합기(7) 및 UHF-VHF 고주파전파신호증폭기(8)를 연결하여 고주파출력신호(RFC)를 얻은 후, 고주파전파신호와 저주파음성신호의 혼합회로를 구성하여 전송하는 방법으로서, 고주파전파신호와 저주파음성신호가 혼합기(2)로 흐른다.As shown in FIG. 1, the low frequency audio signal (AFC), UHF antenna 3, VHF high channel antenna 4, , VHF low channel antenna (5), VHF high mixer (6), UHF-VHF mixer (7) and UHF-VHF high frequency signal amplifier (8) to obtain a high frequency output signal (RFC) Thereafter, as a method of constructing and transmitting a mixed circuit of a high frequency radio wave signal and a low frequency audio signal, a high frequency wave signal and a low frequency audio signal flow to the mixer 2.

이때, 고주파전파신호와 저주파음성신호의 합성장치인 회로도(제 2 도)의 입력단자(14)에 가해진 저주파음성신호는 저주파음성신호와 통과코일(17) (18)을 통과하여 출력단자(16)으로 출력되며, 고주파입력단자(15)에 가해진 고주파전파신호는 통과콘덴서(20)를 통과하여 출력단자(16)의 저주파음성신호와 혼합된다(이때의 임피던스는 75Ω으로 동작하며, 회로의 구성만으로 동작하므로 전원은 필요치 않는다).At this time, the low frequency audio signal applied to the input terminal 14 of the circuit diagram (FIG. 2), which is a device for synthesizing a high frequency radio wave signal and a low frequency audio signal, passes through the low frequency audio signal and the pass coils 17 and 18 and outputs the output terminal 16. The high frequency propagation signal applied to the high frequency input terminal 15 passes through the pass capacitor 20 and is mixed with the low frequency audio signal of the output terminal 16 (the impedance at this time operates at 75? It only works, so no power is required).

이때, 고주파전파신호는 입력단자(15)에서 저주파음성신호 입력단자(14)측으로 흐르려는 고주파전파신호(RFC)는 저주파음성신호(AFC) 통과코일(17) (18)에 의해 필터(FILTER)되며, 미소하게 흐른 고주파전파신호의 잔류가 있으면 패스콘덴서(19)에 의해 소멸된다.At this time, the high frequency radio wave signal is to flow from the input terminal 15 to the low frequency audio signal input terminal 14 side by a low frequency audio signal (AFC) pass coil 17, 18 filter (FILTER) If there is a residual of the high-frequency propagation signal that flowed minutely, it is extinguished by the pass capacitor 19.

The audio signal and the high frequency signal are first connected to the amplifier of the line high frequency amplifier 9, the input signal 21 of the high frequency signal and the low frequency audio signal separation flow diagram (Fig. 3).

이때, 저주파음성신호는 저주파음성신호통과코일(23) (24)를 지나 출력단자(22)에 흐르게 되며, 한편 입력단자(21)에 흐르고 있는 고주파전파신호는 고주파전파신호 통과콘덴서(26)을 통과하여 고주파전파신호증폭기(30)의 입력단자(28)에 흘러 증폭된 고주파전파신호는 이 고주파전파신호증폭기(30)의 출력단자(29)에서 얻어지며, 이때, 고주파전파신호증폭기(30)의 전원은 증폭기의 자체 AC100V∼220V로 동작하며, 고주파의 임피던스메칭은 각 선로 및 고주파증폭등, 고주파가 통과하는 각부 전체의 임피던스는 75Ω으로 동작한다.At this time, the low frequency audio signal flows through the low frequency audio signal passing coils 23 and 24 to the output terminal 22, while the high frequency signal flowing through the input terminal 21 passes the high frequency signal passing capacitor 26. The high frequency propagated signal passed through and amplified in the input terminal 28 of the high frequency signal amplifier 30 is obtained from the output terminal 29 of the high frequency signal amplifier 30, in which case the high frequency signal amplifier 30 The power supply is operated by the amplifier's own AC100V ~ 220V, and the impedance matching of high frequency is 75Ω by impedance of each part through each line and high frequency amplification.

여기서, 출력된 고주파전파신호는 이와 연결된 고주파전파 통과콘덴서(27)를 통과하여 이 전파는 다시 저주파음성신호와 합성되는 출력단자(22)로 흘러 혼합되어 흐르며, 이 양신호는 다시 임피던스 75Ω 동축케이블을 타고 수신처로 흘러 아파트내의 고주파증폭기(제 7 도) (88)의 입력단자에 흘러 이 양신호의 신호분리흐름 및 증폭과정은 상술한 바와 같이 고주파전파신호와 저주파음성신호의 신호분리흐름회로도(제 3 도)의 전과정과 같은 작용을 거쳐 수신처 계통도(제 7 도)아파트내의 고주파증폭기(88)의 출력단자에 혼합되어 흐르며, 제 3 도 고주파전파신호와 저주파음성신호는 신호분리흐름회로도(제 4 도)의 입력단자(31)에 접속한다.Here, the output high frequency radio wave signal passes through the high frequency radio wave pass capacitor 27 connected thereto, and the radio wave flows to the output terminal 22 which is combined with the low frequency audio signal. The signal separation flow and amplification process of the two signals flows to the input terminal of the high frequency amplifier (Fig. 7) 88 in the apartment, and flows to the receiving destination as described above. Through the same process as in Fig. 7), it is mixed with the output terminal of the high-frequency amplifier 88 in the destination system diagram (Fig. 7) apartment, and the high-frequency propagation signal and the low-frequency audio signal are separated from the signal flow diagram (Fig. 4). Is connected to the input terminal 31 of
