WebChirp译名:啁啾(读音:“周纠”),是通信技术有关编码脉冲技术中的一种术语,是指对脉冲进行编码时,其载频在脉冲持续时间内线性地增加,当将脉冲变到音频地,会发出一种声音,听起来像鸟叫的啁啾声,故名“啁啾” … 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 … 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, i.e., their power spectra are alike but the phase spectra are distinct.
