Description

양립식 AM 스테레오 방송 시스템Compatible AM Stereo Broadcasting System

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 단일의 반송파 신호에 직각(quadrature)으로 진폭 변조된 2개의 신호를 송수신하기 위한 종래의 방송 시스템의 블록 다이어그램. 제2도는 제1도에 표시한 시스템의 송신 신호의 반송파와 측파대를 나타내는 페이저(phasor) 다이어그램. 제3도는 본 발명에 의하여 구성한 AM 스테레오 시스템의 블록다이어그램.1 is a block diagram of a conventional broadcast system for transmitting and receiving two signals amplitude-modulated quadrature to a single carrier signal. FIG. 2 is a phasor diagram showing the carrier and sidebands of the transmission signal of the system shown in FIG. 3 is a block diagram of an AM stereo system constructed in accordance with the present invention.

Claims (1)

제1, 제2 정보신호에 해당하는 신호정보가 직각을 이루게 송신되고 단청 및 스테레오 동작을 위해 양립하는 통신시스템에 있어서, 상기 제1, 제2 정보신호의 산술적인 합성에 따라 진폭 변조되고, 탄젠트값이 진폭 변조된 반송파의 포락선에 대한 제1, 제2 정보 신호간의 차이의 비율인 각도에 따라 위상 변조되는 단일 반송파를 발생시키기 위한 송신기(30)와; 상기 반송파를 수신하여 스테레오 동작을 위해 직각을 이룬 제1, 제2 정보신호를 복조시키기 위한 수신기(33)로 구성되어 있으며, 상기 반송파가 실제적인 왜곡을 가져옴이 없이 수신 및 직접적인 단청 재생을 위해 충분히 양립하는 특징을 지닌 양립식 AM 스테레오 방송 시스템.In a communication system in which signal information corresponding to first and second information signals is transmitted at right angles and compatible for mono and stereo operations, amplitude modulation is performed according to an arithmetic synthesis of the first and second information signals, and tangent. A transmitter 30 for generating a single carrier whose value is phase modulated according to an angle that is a ratio of the difference between the first and second information signals with respect to the envelope of the amplitude modulated carrier; And a receiver 33 for demodulating the first and second information signals at right angles for stereo operation by receiving the carrier, which is sufficient for reception and direct mono playback without causing actual distortion. Compatible AM stereo broadcasting system with compatible features. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
