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 . [ 1 ] It is commonly applied to sonar , radar , and laser systems, and to other applications, such as in spread-spectrum communications (see chirp spread spectrum ).
Chirp was launched in 2019, and is owned and operated by the founders of BookBub, an online book discovery service. [5] [6] Although Chirp was launched more recently, BookBub and its parent company Pubmark Inc. have been around since 2012, when it was founded by Josh Schanker and Nicholas Ciarelli.
CHIRP (Continuous High-resolution Image Reconstruction using Patch priors) is a Bayesian algorithm used to perform a deconvolution on images created in radio astronomy. The acronym was coined by lead author Katherine L. Bouman in 2016.
The spectrum of a chirp pulse describes its characteristics in terms of its frequency components. This frequency-domain representation is an alternative to the more familiar time-domain waveform, and the two versions are mathematically related by the Fourier transform.
In digital communications, chirp spread spectrum (CSS) is a spread spectrum technique that uses wideband linear frequency modulated chirp pulses to encode information. [1] A chirp is a sinusoidal signal whose frequency increases or decreases over time (often with a polynomial expression for the relationship between time and frequency).
Chirp is a Canadian animated children's television series created by J.J. Johnson. The series is based on the Canadian children's magazine Chirp. It was previewed on Kids' CBC on March 6, 2015, and premiered on April 20. [1] A Spanish dubbed version start airing on V-me in the United States in 10 May 2019. [citation needed]
