现代广播接收机的一个显著特点——灵敏度高又具有各种高频源。由于单位空间内使用机器的密度增加,各频段使用率提高,造成干扰增多、增强。因此对每一个电子产品都要求满足电磁兼容性。随着广播接收机生产水平的不断提高,近来十分重视电磁兼容性干扰特性的改善。下面我们来探讨一下,干扰的种类并着重论述电磁辐射干扰抑制技术。
One notable feature of modern broadcast receivers - high sensitivity and high frequency sources. Due to the increased density of machines used per unit space, the utilization rate of each frequency band is increased, causing more interference and increasing. Therefore, every electronic product is required to meet the electromagnetic compatibility. As the production level of broadcast receivers continues to increase, much attention has recently been given to the improvement of electromagnetic compatibility interference characteristics. Here we explore, the type of interference and focus on electromagnetic interference suppression technology.
