This paper investigates various combined frequency interference in integrated and double-converted transceivers, and points out that the reason is the non-linearity of frequency mixer and amplifier. 研究了一体化二次变频收发信机中各种组合频率干扰的产生原因:主要是由于混频器和放大器的非线性。
In the control of the general garbage incineration effect, it have adopted fuzzy theory of the artificial intelligence. It combined fuzzy control with the control of the PID in order to realize the effective control of the change and non-linearity and strong coupling system. 在垃圾总体焚烧效果的控制中,采用了人工智能的模糊数学理论,将模糊控制和PID控制相结合,实现对时变、非线性、强耦合系统的有效控制。
