Line 6: In [[Television program\|television]], unlike monophonic radio, at least two signals should be transmitted; [[audio signal\|audio]] (AF) and [[video signal\|video]] (VF) signals. Transmitting those signals by means of separate [[transmitters]] and [[Antenna (radio)\|antenna systems]] is a very costly solution., ~~Because~~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 the [[split sound system]], is also quite costly. But if the signals are combined at an earlier stage, the number of costly outer stages is reduced. The same logic also applies to [[television receiver\|receiver]] sets. If the modulated signal is separated just before the [[Cathode ray tube\|picture tube]] the number of separate stages for AF and VF is ~~minimum~~minimized. This common signal processing system is known as the intercarrier system. == Intercarrier as used in TV transmitters ==
