Abstract
An increase in usable carrier frequency signals within a frequency band is achieved by identifying each carrier frequency signal or channel, not only by its base or reference frequency, but also by a rate of change of the carrier frequencies, such that for each carrier frequency assignment, an additional number of transmission channels, each having a different linear rate of change of frequency starting simultaneously from the reference carrier frequency, is provided where the instantaneous carrier frequency of these channels changes continuously over the frequency band, but each with a different incremental rate of change. Reception comes from tuning a receiver to the reference carrier frequency which adjusts automatically to the frequency reached at that time by a selected carrier frequency signal and then changing the tuning circuit at the same rate as the selected carrier frequency signal changes frequency starting from the predetermined base or reference frequency.
