Abstract
A channel transmission characteristic obtaining method and apparatus, where the method includes obtaining transmission characteristic curves of at least two channels in a cable modem in a channel scanning manner, where the at least two channels form one contiguous frequency band, and frequencies corresponding to the transmission characteristic curves of the at least two channels include frequency values on a same order of magnitude, and amplitude values on a same order of magnitude, translating the transmission characteristic curves of the channels in an amplitude direction, to make amplitudes corresponding to same frequencies on all transmission characteristic curves overlapped in order to form one continuous curve, and setting the continuous curve as a transmission characteristic curve of the contiguous frequency band.
