Pour une porteuse-son modulée en fréquence par un signal de basse fréquence, la fréquence du battement obtenu varie en fonction du signal modulant. Pour extraire ce dernier, il suffit d'utiliser un circuit discriminateur de phase ou de rapport. Le signal de battement peut être prélevé immédiatement après le détecteur vidéo ou après l'amplificateur pour vidéofréquences.  1, fiche 1, Français, - d%C3%A9tecteur%20vid%C3%A9o

The horizontal and vertical sync pulses that form part of the composite video signal are separated in the sync separator. The composite video signal is either taken from the video detector output or after one stage of video amplification. A sync separator is a clipper that is suitably biased to produce output, only during sync pulse amplitude of the video signal. In some receivers, a noise gate precedes the sync separator. This suppresses strong noise pulses if present in the video signal.  3, fiche 2, Anglais, - synchronization%20separator

The main units of the AIC are : the focal plane assembly(FPA), equipped with a back-thinned illuminated CCD matrix and a front-end amplifier, provides the optical signal detection. A thermoelectric peltier cooler under the detector sets the operating point at-25°C ± 100 mK, the detection box(BD) which supplies the FPA with the necessary electrical signals to operate the CCD. It generates the clock waveforms from the VEU signals and filters the supplied voltage from the DSU, the video electronics unit(VEU) which processes the analog signal coming from the FPA, digitizes it on 12 bits before passing it on in serial processing to the science data processing subsystem(SDPSS). It also provides the DBs with the primary clock signal. The power conditioning of the VEU is located in the same unit, the detection supply unit(DSU) delivers relevant stabilized voltages to the 5 DUs and power to thermo-coolers from the main supply feeder of the instrument.  2, fiche 4, Anglais, - analog%20imaging%20chain
