Modifying the spectral energy content of a data bus

An electronic device, comprising:

• a phasor generator to obtain a present bit of data to be transmitted over the data bus and estimate a spectral energy contribution of the present bit of data at a frequency of interest;
• and
• an inversion encoder to:
• determine what effect inverting the present bit of data will have on a net spectral energy of the data bus at the frequency of interest when the present bit of data is transmitted over the data bus;
• and
• generate an inversion signal to send to a selective inverter, wherein a value of the inversion signal is determined based, at least in part, on whether inverting the present bit of data reduces the net spectral energy of the data bus at the frequency of interest.

A non-transitory, tangible, computer-readable medium, comprising instructions to direct a processor to:

• obtain a bit of data to be transmitted over a data bus and estimate a spectral energy contribution of the bit of data at a frequency of interest;
• determine what effect inverting the bit of data will have on a net spectral energy of the data bus at the frequency of interest when the bit of data is transmitted over the data bus;
• and
• invert the bit of data to generate an inverted bit and transmit the inverted bit over the data bus if inverting the bit of data reduces the net spectral energy of the data bus at the frequency of interest.
