摘要：
A method is provided that includes transmitting data to a backplane from a first communication module simultaneously on a first pair of operating frequencies, where the first pair of operating frequencies includes first and second operating frequencies. The method further provides that a −3 dB point of a first electromagnetic emission spectrum peak originating from transmission of the data at the first operating frequency is outside a −3 dB point of a second electromagnetic emission spectrum peak originating from transmission of the data at the second operating frequency.
