TV ghost-image eliminating technique and the relevant circuits is realized by analog signal circuits and characterized by the following: video signal is transmitted in 2 channels, one is for transmitting main TV signal which contains an obvious interfering ghost signal; the other is for processing the main video signal with reversed polarity but same amplitude occuring simultaneously with the ghost signal. The signals from the 2 channels are sent to summing amplifier and, as the result of summing, the ghost signal will be eliminated. Because of its simple structure, reliability and low cost, the invention is easy to operate and easy to be promoted. It may eliminate the positive or negative polarity ghost-signals which are within 100ns-400ns of the main image. |
