我們常說要解決問題就要找到事情的起因，也就是源頭。日常生活中的噪聲源，也是源頭。村田濾波器代(dai)理商告訴(su)你，我們日常(chang)生活有哪些常(chang)見的(de)噪聲源。

我們生(sheng)活(huo)中噪聲源有信號、電(dian)(dian)(dian)(dian)源、浪涌這三種。信號很(hen)好(hao)理解，你可以理解為(wei)手機信號，無線電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)波都可以。電(dian)(dian)(dian)(dian)源指得是(shi)(shi)開(kai)關電(dian)(dian)(dian)(dian)源，電(dian)(dian)(dian)(dian)源開(kai)關瞬間(jian)會(hui)產生(sheng)電(dian)(dian)(dian)(dian)流沖(chong)擊(ji)大。靜電(dian)(dian)(dian)(dian)放電(dian)(dian)(dian)(dian)或開(kai)關切換而意外產生(sheng)的過高電(dian)(dian)(dian)(dian)壓或電(dian)(dian)(dian)(dian)流稱為(wei)浪涌。浪涌和電(dian)(dian)(dian)(dian)源很(hen)像，但是(shi)(shi)有區別的，典型的浪涌是(shi)(shi)靜電(dian)(dian)(dian)(dian)浪涌、開(kai)關浪涌和雷擊(ji)浪涌等。
