Whereas a passband signal is also modulated so that it occupies higher frequencies (compared to a baseband signal which is bound to the lowest end of the spectrum, see line coding), it is still occupying a single channel.
Budući da je signal propusnog opsega (engl. passband) takođe moduliran tako da zauzima veće frekvencije (u poređenju sa signalom baznog opsega (engl. baseband) koji je vezan za najniži kraj spektra), on ipak zauzima jedan kanal.
