ABSTRACT:
In a television transmitter having separate picture- and sync-modulated r.f. amplification, the sync-modulated r.f. signal is derived from the picture-modulated signal using a modulator controlled by the video sync signal conventionally present in the transmitter. This simplifies the construction of the transmitter, and is particularly applicable to solid-state amplifier transmitters.
