frequency-slope modulation frequency-slope modulation[′frē·kwən·sē ‚slōp ‚mäj·ə′lā·shən] (communications) Type of modulation in which the carrier signal is swept periodically over the entire width of the band, much as in chirp radar; modulation of the carrier with a voice or other communication signal changes the bandwidth of the system without affecting the uniform distribution of energy over the band. |
