WebChirp Slope Keying (CSK) is a digital chirp modulation scheme in which binary data are represented using chirps of increasing and decreasing frequencies versus time. In other wo rds, an up chirp represents a 1 while a down chirp represents a 0. WebAs a spread-spectrum system, chirp slope keying (CSK) uti-lizes a data-modulated signal with its energy spread over a bandwidth that is much greater than the rate of information be-ing transmitted. Chirp slope keying Chirp signals in digital communications were apparently origi-nally suggested by M. R. Winkler. 3. in 1962and then abandoned.
