摘要
根据Nyquist准则，导出PAL信号的内插函数，并按此准则讨论常规电视系统中图像的重现质量，建立一种改善图像质量的插值方式，对其插值原理和滤波特性进行了数学分析。
According to Nyquist criterion， interpolating function for PAL signals is derived and TV image reproducing quality in the conventional television system is discussed． An interpolating method used to improve TV image quality is presented． The interpolating principle and filtering characteristic are mathematically analyzed．
