... @fel.cvut.cz 1 Abstract — The Dual-Band Band Limited Signal (DBBLS) is signal processing. For instance in [11] is patented the a signal with its power spectral density consisting of two computationally efficient realization of the discriminator separate lobes. Signals that can be considered as DBBLS are function of the signal modulated on single ...
