北京邮电学院张家谋教授等研制的电视消重影电路技术1989年11月1日在北京通过鉴定.由于城市现代化和高层建筑的增多或地形的复杂,造成电视机屏幕上的重影越来越多,致使图象质量降低,收看效果不佳.张家谋教授等研制的模拟电视机消重影电路技术,可抵消6.4μs 以内的重影,抵消幅度和极性可调,对电视机接收来的任何信号所产生的重影,可抵消90%以上,满足实用要
Beijing Institute of Posts and Telecommunications Zhang Jiamou et al. Invented the TV deghosting circuit technology passed the appraisal in Beijing on November 1, 1989. Due to the increase of the urban modernization and high-rise buildings or the complex terrain, the ghost images on the television screen are more and more , Resulting in reduced image quality, watching ineffective.Developed by Professor Zhang and other analog TV anti-ghosting circuit technology can offset the ghost within 6.4μs offset and amplitude adjustable, any received to the TV Ghosting generated by the signal can offset more than 90% to meet the practical needs
