Such diplexers are expensive and bulky. In intercarrier system where the combining is achieved at a low level stage no diplexer is used. Whereas in intercarrier system RF amplifiers are common for both the visual and aural signals, in split sound system visual and aural transmitters have separate RF amplifiers (tetrodes or klystrons).
A diplexer is a device used to combine two signals occupying different frequency bands into a single signal. This is usually to enable two signals to be transmitted simultaneously on the same communications channel, or to allow transmitting on one frequency while receiving on another. (This specific use of a diplexer is called a duplexer.)
In TV receivers, the received radio frequency signal is converted to IF in tuner and then demodulated. The output of the demodulator consists of a VF and an aural signal which is in fact an FM subcarrier modulated by AF. (The subcarrier is 5.5 MHz in system B and 4.5 MHz in system M ) The aural signal and the VF are separated by a simple filter.
