WebChirp is a critical element in high bit rate lightwave systems because it can interfere in the limit of the system distance [1]. External modulators offer a way to reduce or eliminate chirp because the laser source is held in the … 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 … 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 … See more Chirp modulation Chirp modulation, or linear frequency modulation for digital communication, was patented by See more • Online Chirp Tone Generator (WAV file output) • CHIRP Sonar on FishFinder • CHIRP Sonar on FishFinder See more Linear In a linear-frequency chirp or simply linear chirp, the instantaneous frequency $${\displaystyle f(t)}$$ varies exactly linearly with time: $${\displaystyle f(t)=ct+f_{0}}$$, where See more A chirp signal shares the same spectral content with an impulse signal. However, unlike in the impulse signal, spectral components of the chirp signal have different phases, … See more • Chirp spectrum - Analysis of the frequency spectrum of chirp signals • Chirp compression - Further information on compression techniques • Chirp spread spectrum - A part of the wireless telecommunications standard IEEE 802.15.4a CSS See more
