读了《家庭电子》今年第7期《电源滤波器试用记》一文后,深有同感。笔者曾在道奇收音机上采用音响专用的30A滤波器,并将外壳可靠接地,但装上后无明显区别。将电源滤波器装在电子镇流器或可控硅调节器电路上,效果却非常明显。上述两类电器工作时,通常对无线电设备干扰很大,在电路中串上滤波器(一定要装在旁边),同一房间内音像设备的干扰杂音和雪花点明显减少,图像和声音质量明显提高,对干电池
Read the “home electronics” seventh issue of this year, “Power Filter Trial Notes,” a text, feel the same. I used to use the 30A filter for the sound system on the Dodge radio, and grounded the case reliably, but there was no obvious difference when installed. The power filter installed in the electronic ballast or thyristor circuit, the effect is very obvious. The above two types of electrical work, the radio equipment is usually very disturbing, in the circuit string filter (must be installed next to), the same room audio and video equipment noise and snowflakes significantly reduce the noise, significantly improve the quality of images and sound On the dry battery
