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.
