System for the transmission of a composite television signal |
摘要 |
The transmission system essentially involves separate amplification followed by a combination under predetermined conditions of relative amplitude and phase, of a carrier signal modulated by the video-frequency information and having a reduced carrier level with the same unmodulated carrier, thus permitting a considerable improvement in both efficiency and reliability of conventional transmitters.
