本文介绍了德意志联邦共和国的双伴音与立体声电视广播发射与接收技术。对双载波法和FM/FM法作了对比,叙述了联邦德国选用双载波法的依据以及立体声信号新的编码方法及其优点,同时还讨论了工作于频率偏置的同频道电视发射机对选用不同双伴音制式的伴音信噪比的影响。对接收机信号处理也作了简要介绍。
This article describes the dual sound and stereo broadcast transmission and reception techniques in the Federal Republic of Germany. The dual-carrier method and the FM / FM method are compared. The basis of the double-carrier method used by the Federal Republic of Germany and the new encoding method of the stereo signal and its advantages are also described. The co-channel television transmitters working on the frequency offset are also discussed Choose different double sound system sound signal-to-noise ratio. The receiver signal processing also made a brief introduction.
