Abstract
An apparatus for reducing electromagnetic interference is provided. The apparatus includes a receiving module, a first comparing module, and a frequency spreading module. The receiving module receives a first signal with a first frequency and a second signal with a second frequency. The first comparing module is used for comparing the first frequency and the second frequency. The frequency spreading module is operated by a comparing result of the first comparing module. If the first frequency is higher than the second frequency, the frequency spreading module up-spreads the first frequency and down-spreads the second frequency.
Claims14
A method for reducing electromagnetic interference in an electronic device, comprising:
- (a) receiving a first signal with a first frequency and a second signal with a second frequency;
- (b) comparing the first frequency and the second frequency;
- (c) if the first frequency is higher than the second frequency, up-spreading the first frequency of the first signal to generate a third signal and down-spreading the second frequency of the second signal to generate a fourth signal;
- and
- (d) transmitting the third signal and the fourth signal to the electronic device.
