摘　　要：为了适应数字电视地面广播的发展,电视发射技术从模拟向数字传输转化,最大程度地节约了成本,从数字电视发射机对功率放大器的特殊要求出发,为达需要将电视发射技术,从虚拟转变为数字化,节约成本投入。因此,文章以电视发射机模数过渡中过滤放大器作为主要的叙述内容,对其中的措施以及出现的问题进行了浅析。In order to adapt to the development of digital television terrestrial broadcasting,the TV launching technology is successfully transferred from analog to digital, and the cost is saved to the greatest extent.From the special requirements of the digital TV transmitter to the power amplifier, the TV launching technology is changed from virtual to digitization ,and then the cost is saved.Input,from the digital TV transmitter to the requirements of power amplifier as the center,to carry out reform. Therefore, this paper took the filter amplifier in the transition of the TV transmitter as the main description, and made a shallow analysis of the measures and the problems.
