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. This type of modulation employs sinusoidal waveforms whose instantaneous frequency increases or decreases linearly … See more 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, … See more Linear In a linear-frequency chirp or simply linear chirp, the instantaneous frequency $${\displaystyle f(t)}$$ varies exactly linearly with time: 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. Dispersion of … See more • Online Chirp Tone Generator (WAV file output) • CHIRP Sonar on FishFinder • CHIRP Sonar on FishFinder 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 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 WebThe window will have nulls at f − 1 / T and f + 1 / T, where f is the tone's frequency. Because the chirp rate is R = B / T, the time resolution corresponding to a frequency resolution of 1 T is 1 / T B / T = 1 B. Plugging this into the range resolution equation, we have Δ r = c / ( 2 B).
