RF Modulation: Crash Course For Hackers Hackaday
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. WebA chirpis a signalin which the frequencyincreases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirpis used interchangeably with sweep signal.[1] It is commonly applied to sonar, radar, and lasersystems, and to other applications, such as in spread-spectrumcommunications (see chirp spread spectrum). chromium inhalation
