ABSTRACT:
An apparatus such as a television signal receiver is capable of removing adjacent channel energy for extremely different desired channel bandwidths and varying adjacent channel conditions. According to an exemplary embodiment, the apparatus includes a digital signal source for providing a digital signal having a symbol rate, and a plurality of symbol shaping filters. A selected one of the symbol shaping filters is used to filter the digital signal and generate a filtered digital signal based on the symbol rate.
