Sahihi ya umeme katika nyaya za umeme ni daima kipengele muhimu ya vifaa vya umeme, wote Analog na Digital . Katika kesi ya nyaya za Analog kawaida ina athari kubwa juu ya aina mbalimbali ya kelele kwamba ni yaliyojitokeza katika mfumo, ambayo ni alijiinua na kuzalishwa katika kiwango milele zaidi (hii inaweza kuonekana katika kila aina ya vifaa vya redio – video) .
