摘要
数字功放的工作原理决定了它会产生较严重的电磁兼容(EMC)问题,并且一直以来这种EMC问题都是比较难以解决的。根据数字功放的原理,从元器件选择和PCB设计的角度探讨了数字功放的电磁骚扰抑制方法,并给出了一个实际的整改案例来加以说明。
Digital amplifiers usually have serious EMC problems due to its working principle, which are difficult to resolve. In this paper, the suppression of electromagnetic disturbance of digital amplifiers is discussed in terms of component selection and PCB design based on the principles of digital amplifiers. And an example is given to illustrate the proposed method.
