Abstract
Frequency spectrums are determined for all possible codes given a predetermined number of bits in a code. A subset of these codes is formed based on spectral properties of codes in a desired frequency band. This subset of code is then used to encode data prior to transmission over a high-speed data bus to reduce undesirable emissions on targeted frequency bands.
