WebSep 15, 2006 · Binary chirp signals, or what Berni 4 called linear frequency sweeping (LFS), compared favorably to frequency-shift-keying (FSK) and phase-shift-keying (PSK) … A chirp is a signal in which the frequency increases (up-chirp) or decreases (down-chirp) with time. In some sources, the term chirp is used interchangeably with sweep signal. It is commonly applied to sonar, radar, and laser systems, and to other applications, such as in spread-spectrum communications … See more The basic definitions here translate as the common physics quantities location (phase), speed (angular velocity), acceleration (chirpyness). If a waveform is defined as: See more A chirp signal can be generated with analog circuitry via a voltage-controlled oscillator (VCO), and a linearly or exponentially ramping control voltage. It can also be generated See more Chirp modulation Chirp modulation, or linear frequency modulation for digital communication, was patented by Sidney Darlington in 1954 with significant later work performed by Winkler in 1962.

WebII. M-ary Modulation Signals A general chirp signal is represented by a starting frequency, a chirp rate, and a chirp duration[3]. A novel binary chirp modulation is presented in Ref.[9] where a linear function is adopted as the integral impulse for the time-varying function of phase. Now we extend the binary chirp modulation to M-ary WebDefined this way, chirps are intended to serve as models for monocomponent signals modulated in both amplitude and frequency, their “instantaneous” frequency being …
