Adjective
intercarrier (not comparable)
Between carriers (in any of several contexts)
One particular advantage of intercarrier sound is that when the front panel fine tuning knob is adjusted, the sound carrier frequency does not change with the tuning, but stays at the above-mentioned offset frequency. Source: Internet
In newer sets, this new carrier at the offset frequency was allowed to remain as intercarrier sound, and it was sent to an FM demodulator to recover the basic sound signal. Source: Internet
When intercarrier sound was invented later in 1948, not completely shutting off the carrier had the side effect of allowing intercarrier sound to be economically implemented. Source: Internet
