Abstract
A method and apparatus are provided for use in a multi-channel digital transmitter and receiver. A filtering process is accomplished by conditioning portions of a digitized signal during digital signal processing by integrating, taking the difference of, and multiplying portions of the digitized signal. The filtering process may be used in conjunction with a receiving process to generate a digitized channel signal by conditioning the digitized signal and subsequently Fourier transforming the conditioned portions of the digitized signal. Alternatively, the filtering process may be used in conjunction with a transmitting process by inverse Fourier transforming a plurality of digitized information signals to be transmitted to generating a composite digitized signal and subsequently conditioning the composite digitized signal.
