我们知道电视发射机的非线性失真主要产生在末级功率放大器,无论是模拟电视发射机还是数字电视发射机,都要求末级功率放大器具有高增益、高动态、高线性。但因为功放管是非线性元件,因此其状态总会随着环境温度以及工作时间而变化,在对信号的放大时产生非线性失真。对于非线性的校正,模拟电视发射机与数字电视发射机基本都是在中 We know that the nonlinear distortion of TV transmitters mainly occurs in the final power amplifier. Whether it is an analog TV transmitter or a digital TV transmitter, the final power amplifier is required to have high gain, high dynamic and high linearity. However, because the power amplifier tube is a non-linear component, its state will always change with the ambient temperature and working time, causing nonlinear distortion when amplifying the signal. For non-linear correction, analog TV transmitters and digital TV transmitters are basically in
