  • Apparatus and method for preventing occurrence of electromagnetic interference in portable terminal
    Patent number: 8989689
    Abstract: An apparatus and method for setting a modulation frequency within a non-use frequency range so as to reduce ElectroMagnetic Interference (EMI) occurring during frequency modulation in a portable terminal are provided. The apparatus includes a controller and a frequency set unit. At frequency modulation, the controller determines whether a modulation frequency corresponds to a frequency inducing EMI. In a case where it is determined that the modulation frequency corresponds to the frequency inducing EMI, the frequency set unit resets the modulation frequency.
