Abstract
A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to monitor spectral characteristics of a target channel, a first channel and a second channel, where the target channel is of a digital terrestrial television system, where the first channel is an upper adjacent channel to the target channel, and where the second channel is a lower adjacent channel to the target channel. The controller is adapted to generate an emission mask based on the monitored spectral characteristics and detect interference between the target channel and at least one of the first and second channels based at least in part on the emission mask. Other embodiments are disclosed.
