종래의 음성다중 방송신호 선택회로에 있어서는 스위칭 접적소자를 이용하고 있으므로, 전체 구조가 복잡하여 제품의 원가가 상승되는 결점이 있었다.In the conventional voice multiplexing signal selection circuit, since a switching integrated element is used, the overall structure is complicated, resulting in a cost increase of the product.

본 고안은 이러한 점을 감안하여, 주음성, 부음성, 주/부 음성을 선택하여 수신할 수 있게 오아게이트를 이용한 간단한 회로를 안출한 것으로, 이를 첨부된 도면에 의하여 보다 상세히 설명하면 다음과 같다.In view of this point, the present invention devised a simple circuit using an oragate to select and receive a main voice, a sub voice, and a main / sub voice, which will be described in detail with reference to the accompanying drawings. .

첨부된 도면에 도시한 바와같이, 2개국어 방송신호 수신제어용 집적소자(1)의 출력단자(Q1)를 절환스위치(SW1) 및 아날로그 스위치(AS1)의 제어단자에 접속하여, 그 절환스위치(SW1)의 고정접점(a1)은 절환스위치(SW2) 및 오아게이트(OR3)의 일측 입력단자에 접속하고 고정접점(b1)은 오아게이트(OR1)의 타측 입력단자 및 오아게이트(OR2)의 일측 입력단자에 공통 접속하며, 그 아날로그 스위치(AS1)의 가동접점을 오아게이트(OR3),(OR4)의 타측 입력단자에 공통 접속함과 아울러 다이오드(D1)를 통하여 2개국어 방송신호 수신제어용 집적소자(1)의 출력단자(Q2)에 접속하고, 또한 절환스위치(SW2)의 고정접점(a2),(b2)을 오아게이트(OR1)의 일측 입력단자 및 오아게이트(OR2)의 타측 입력단자에 각각 접속하여 오아게이트(OR1)의 출력단자를 오아게이트(OR4)의 일측 입력단자에 접속하고, 오아게이트(OR4),(OR2),(OR3)의 출력단자를 아날로그 스위치(AS2),(AS3),(AS4)의 제어단자를 각각 접속하며, 그 아날로그 스위치(AS2),(AS3)의 가동접점을 주, 부 음성출력회로(2)(3)에 접속함과 아울러 아날로그 스위치(AS2),(AS4)의 고정접점을 좌출력회로(4)에 공통 접속하고 아날로그 스위치(AS2)의 고정접점과 아날로그 스위치(AS4)의 가동접점을 우출력회로(5)에 공통 접속하여 구성한 것으로, 여기서 2개국어 방송신호 수신제어용 집적소자(1)는 2개국어 방송시에만 그의 출력단자(Q1),(Q2)에 고전위 신호를 출력하고, 아날로그 스위치(AS1-AS4)는 그의 제어단자에 고전위 신호가 인가될때 단락되게 되어 있다.As shown in the accompanying drawings, the output terminal Q 1 of the bilingual broadcast signal reception control integrated device 1 is connected to the control terminal of the switching switch SW 1 and the analog switch AS 1 , and a fixed contact (a 1) is a change-over switch (SW 2) and Iowa coupled to one input terminal of a gate (OR 3) and the other input of the fixed contacts (b 1) is Iowa gate (OR 1) of the change-over switch (SW 1) Common connection is made between the terminal and the one input terminal of the OR gate OR 2 , and the movable contact of the analog switch AS 1 is commonly connected to the other input terminal of the OR gates OR 3 and OR 4 and the diode (D 1 ) is connected to the output terminal (Q 2 ) of the bilingual broadcast signal reception control integrated device (1), and also the fixed contacts (a 2 ) and (b 2 ) of the switching switch (SW 2 ). The output terminal of the OR gate OR 1 is connected to one input terminal of the gate OR 1 and the other input terminal of the OR gate OR 2 , respectively. Bit coupled to one input terminal of the (OR 4), and Iowa gate (OR 4), (OR 2 ), (OR 3) an analog switch (AS 2) the output terminal of, (AS 3), (AS 4) of The control terminals are connected respectively, and the movable contacts of the analog switches AS 2 and AS 3 are connected to the main and negative audio output circuits 2 and 3, and the analog switches AS 2 and AS 4 are connected. ) Is connected to the left output circuit 4 in common, and the fixed contact of the analog switch AS 2 and the movable contact of the analog switch AS 4 are connected to the right output circuit 5. The integrated broadcast signal reception control element 1 outputs a high potential signal to its output terminals Q 1 and Q 2 only during bilingual broadcasting, and the analog switches AS 1 to AS 4 control it. It is shorted when a high potential signal is applied to the terminal.

이와 같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.

2개국어 방송시에는 상기와 같이 2개국어 방송신호 수신제어용 집적소자(1)의 출력단자(Q1),(Q2)에서 고전위 신호가 출력되므로 아날로그 스위치(AS1)가 단락되어 오아게이트(OR3),(OR4)의 타측 입력단자에 저전위 신호가 인가된다.Bilingual broadcast when the output terminal of a bilingual broadcast signal reception control integrated device (1) as described above (Q 1), since the high potential signal output from the (Q 2) is an analog switch (AS 1) is short-circuited Iowa The low potential signal is applied to the other input terminal of the gates OR 3 and OR 4 .

이러한 상태에서 절환스위치(SW1),(SW2)를 그의 고정접점(a1),(a2)에 단락하면 오아게이트(OR1),(OR3)의 일측입력단자에 고전위 신호가 인가되므로 그의 출력측에 고전위 신호가 출력되고, 따라서 오아게이트(OR1)에서 출력된 고전위 신호는 오아게이트(OR4)를 통하여 아날로그 스위치(AS2)를 단락시키고, 오아게이트(OR3)에서 출력된 고전위 신호는 아날로그 스위치(AS4)를 단락시키므로, 주음성 출력회로(2)에서 출력된 주음성 신호는 아날로그 스위치(AS2)를 통하여 좌출력 회로(4)에 공급됨과 동시에 아날로그 스위치(AS2)를 통한 주음성 신호는 아날로그 스위치(AS4)를 통하여 우출력회로(5)에 공급된다.In this state, if the switching switches SW 1 and SW 2 are short-circuited to their fixed contacts a 1 and a 2 , a high potential signal is generated at one input terminal of the OR gates OR 1 and OR 3 . Since the high potential signal is output to the output side thereof, the high potential signal output from the OR gate OR 1 shorts the analog switch AS 2 through the OR gate OR 4 , and the OR gate OR 3 . Since the high-potential signal outputted from shorts the analog switch AS 4 , the main audio signal output from the main audio output circuit 2 is supplied to the left output circuit 4 through the analog switch AS 2 , and at the same time, The main audio signal through the switch AS 2 is supplied to the right output circuit 5 through the analog switch AS 4 .

이와같이 절환스위치(SW1)(SW2)를 그의 고정접점(a1),(a2)에 단락했을 경우에는 좌, 우출력회로(4),(5)는 주음성신호만 수신할 수 있게 된다. 또한 절환스위치(SW1)를 그의 고정접점(a1)에 단락하고, 절환스위치(SW2)를 그의 고정접점(b2)에 단락하면 오아게이트(OR2),(OR3)의 입력단자에 고전위 신호가 인가되어 그의 출력측에 고전위 신호가 출력되고, 이 고전위 신호는 아날로그 스위치(AS3),(AS4)를 단락시키므로, 부음성출력회로(3)에서 출력된 부음성신호는 아날로그 스위치(AS3)를 통하여 우출력회로(5)에 공급됨과 동시에 아날로그 스위치(AS3)를 통한 부음성신호는 아날로그 스위치(AS4)를 통하여 좌출력회로(4)에 공급된다.In this way, when the switching switch SW 1 (SW 2 ) is shorted to its fixed contacts a 1 and (a 2 ), the left and right output circuits 4 and 5 can receive only the main audio signal. do. In addition, when the switching switch SW 1 is short-circuited to its fixed contact a 1 and the switching switch SW 2 is shorted to its fixed contact b 2 , the input terminals of the OR gates OR 2 and OR 3 are shorted. A high potential signal is applied to the output side, and a high potential signal is output to the output side thereof. The high potential signal shorts the analog switches AS 3 and AS 4 , so that the negative audio signal output from the negative audio output circuit 3 is applied. It is a sub-audio signal through the analog switch (AS 3) at the same time as the right output supply circuit 5 through the analog switch (AS 3) is supplied to the left output circuit 4 via the analog switch (AS 4).

이와같이 절환스위치(SW1)가 그의 고정접점(a1)에 단락되고, 절접스위치(SW2)가 그의 고정접점(b2)에 단락된 상태에서는 좌, 우출력회로(4),(5)는 부음성신호만 수신할 수 있게 된다. 또한 절환스위치(SW1)를 그의 고정접점(b1)에 단락하면, 절환스위치(SW2)는 절환스위치(SW1)로 부터 분리되므로 절환스위치(SW2)의 절환상태에 관계없이 오아게이트(OR1),(OR2)의 입력단자에만 고전위 신호가 인가되어 그의 출력단자에 고전위 신호가 출력되고, 이에따라 아날로그 스위치(AS2),(AS3)가 단락되어 주음성출력회로(2)에서 출력된 주음성신호는 아날로그 스위치(AS2)를 통하여 좌출력회로(4)에 공급되고 부음성출력회로(3)에서 출력된 부음성신호는 아날로그 스위치(AS3)를 통하여 우출력회로(5)에 공급된다.In this way, the switching switch SW 1 is short-circuited to its fixed contact a 1 and the switching switch SW 2 is short-circuited to its fixed contact b 2 . Can receive only the negative audio signal. In addition, when the switching switch SW 1 is shorted to its fixed contact b 1 , the switching switch SW 2 is separated from the switching switch SW 1 , so that the oragate is independent of the switching state of the switching switch SW 2 . A high potential signal is applied only to the input terminals of (OR 1 ) and (OR 2 ) so that a high potential signal is output to the output terminal thereof. Accordingly, the analog switches AS 2 and (AS 3 ) are short-circuited and the main audio output circuit ( The main audio signal output from 2 ) is supplied to the left output circuit 4 through the analog switch AS 2 , and the sub audio signal output from the sub audio output circuit 3 is output right through the analog switch AS 3 . Supplied to the circuit 5.

이와같이 절환스위치(SW1)를 그의 고정접점(b1)에 단락했을 경우에는 절환스위치(SW2)의 절환상태에 관계없이 좌, 우출력회로(4),(5)는 주음성신호 및 부음성신호를 각각 수신할 수 있게 된다.When the switching switch SW 1 is short-circuited to its fixed contact b 1 as described above, the left and right output circuits 4 and 5 are connected to the main audio signal and the negative signal regardless of the switching state of the switching switch SW 2 . Each voice signal can be received.

이상에서와 같이 본 고안은 2개국어 방송시에 주음성신호, 부음성신호, 주/부음성신호를 오아게이트를 이용한 간단한 회로로 선택 수신할 수 있게 되므로 제품의 원가가 절감되는 이점이 있다.As described above, the present invention has the advantage of reducing the cost of the product because it is possible to select and receive the main audio signal, the sub-audio signal, the main / sub-audio signal by a simple circuit using an oar gate when broadcasting in two languages.
