The intercarrier method is a system in television that reduces the cost of transmitters and receiver sets by processing audio and video signals together and minimizing the number of separate stages for audio and video signals. == Transmission of audio and video signals == In television, unlike monophonic radio, at least two signals should be transmitted; audio (AF) and video (VF) signals. Transmitting those signals by means of separate transmitters and antenna systems is a very costly solution. Because every stage must be used twice, one for AF and one for VF. Two separate transmitters, a high power combiner and a common antenna system, known as split sound system, is also quite costly. But if the signals are combined at an earlier stage, number of costly outer stages is reduced. The same logic also applies to receiver sets. If the modulated signal is separated just before the picture tube the number of separate stages for AF and VF is minimum. This common signal processing system is known as intercarrier system. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Intercarrier method」の詳細全文を読む スポンサード リンク
